Each manual file must include the following XML declarations at the top of the file:
<?xml version="1.0" encoding="UTF-8"?> <!-- Reviewed: no -->
XML files from translated languages must also include a revision tag containing the revision of the corresponding English-language file the translation was based on.
<?xml version="1.0" encoding="UTF-8"?> <!-- EN-Revision: 14978 --> <!-- Reviewed: no -->
The maximum line length, including tags, attributes, and indentation, is not to exceed 100 characters. There is only one exception to this rule: attribute and value pairs are allowed to exceed the 100 chars as they are not allowed to be separated.
Indentation should consist of 4 spaces. Tabs are not allowed.
Tags which are at the same level must have the same indentation.
<sect1> </sect1> <sect1> </sect1>
Tags which are one level under the previous tag must be indented with 4 additional spaces.
<sect1>
<sect2>
</sect2>
</sect1>
Multiple block tags within the same line are not allowed; multiple inline tags are allowed, however.
<!-- NOT ALLOWED: -->
<sect1><sect2>
</sect2></sect1>
<!-- ALLOWED -->
<para>
<classname>Zend_Magic</classname> does not exist. <classname>Zend_Acl</classname> does.
</para>
Line termination follows the Unix text file convention. Lines must end with a single linefeed (LF) character. Linefeed characters are represented as ordinal 10, or hexadecimal 0x0A.
Note: Do not use carriage returns (CR) as is the convention in Apple OS's (0x0D) or the carriage return - linefeed combination (CRLF) as is standard for the Windows OS (0x0D, 0x0A).
Empty tags are not allowed; all tags must contain text or child tags.
<!-- NOT ALLOWED -->
<para>
Some text. <link></link>
</para>

</para>
Opening block tags should have no whitespace immediately following them other than line breaks (and indentation on the following line).
<!-- NOT ALLOWED --> <sect1>WHITESPACE </sect1>
Opening inline tags should have no whitespace immediately following them.
<!-- NOT ALLOWED --> This is the class <classname> Zend_Class</classname>. <!-- OK --> This is the class <classname>Zend_Class</classname>.
Closing block tags may be preceded by whitespace equivalent to the current indentation level, but no more than that amount.
<!-- NOT ALLOWED -->
<sect1>
</sect1>
<!-- OK -->
<sect1>
</sect1>
Closing inline tags must not be preceded by any whitespace.
<!-- NOT ALLOWED --> This is the class <classname>Zend_Class </classname> <!-- OK --> This is the class <classname>Zend_Class</classname>
Multiple line breaks within or between tags are not allowed.
<!-- NOT ALLOWED -->

The opening <programlisting> tag must indicate the appropriate "language" attribute and be indented at the same level as its sibling blocks.
<para>Sibling paragraph.</para> <programlisting language="php"><![CDATA[
CDATA should be used around all program listings.
<programlisting> sections must not add linebreaks or whitespace at the beginning or end of the section, as these are then represented in the final output.
<!-- NOT ALLOWED --> <programlisting language="php"><![CDATA[ $render = "xxx"; ]]></programlisting> <!-- OK --> <programlisting language="php"><![CDATA[ $render = "xxx"; ]]></programlisting>
Ending CDATA and <programlisting> tags should be on the same line, without any indentation.
<!-- NOT ALLOWED -->
<programlisting language="php"><![CDATA[
$render = "xxx";
]]>
</programlisting>
<!-- NOT ALLOWED -->
<programlisting language="php"><![CDATA[
$render = "xxx";
]]></programlisting>
<!-- OK -->
<programlisting language="php"><![CDATA[
$render = "xxx";
]]></programlisting>
The <programlisting> tag should contain the "language" attribute with a value appropriate to the contents of the program listing. Typical values include "css", "html", "ini", "javascript", "php", "text", and "xml".
<!-- PHP --> <programlisting language="php"><![CDATA[ <!-- Javascript --> <programlisting language="javascript"><![CDATA[ <!-- XML --> <programlisting language="xml"><![CDATA[
For program listings containing only PHP code, PHP tags (e.g., "<?php", "?>") are not required, and should not be used. They simply clutter the narrative, and are implied by the use of the <programlisting> tag.
<!-- NOT ALLOWED -->
<programlisting language="php"<![CDATA[<?php
// ...
?>]]></programlisting>
<programlisting language="php"<![CDATA[
<?php
// ...
?>
]]></programlisting>
Line lengths within program listings should follow the coding standards recommendations.
Refrain from using require_once(),
require(), include_once(), and
include() calls within PHP listings.
They simply clutter the narrative, and are largely obviated when using an
autoloader. Use them only when they are essential to the example.
Never use short tags
Short tags (e.g., "<?", "<?=") should never be used within programlisting or the narrative of a document.
The tag <classname> must be used each time a class name is represented by itself; it should not be used when combined with a method name, variable name, or constant, and no other content is allowed within the tag.
<para>
The class <classname>Zend_Class</classname>.
</para>
Variables must be wrapped in the <varname> tag. Variables must be written using the "$" sigil. No other content is allowed within this tag, unless a class name is used, which indicates a class variable.
<para>
The variable <varname>$var</varname> and the class variable
<varname>Zend_Class::$var</varname>.
</para>
Methods must be wrapped in the <methodname> tag. Methods must either include the full method signature or at the least a pair of closing parentheses (e.g., "()"). No other content is allowed within this tag, unless a class name is used, which indicates a class method.
<para>
The method <methodname>foo()</methodname> and the class method
<methodname>Zend_Class::foo()</methodname>. A method with a full signature:
<methodname>foo($bar, $baz)</methodname>
</para>
Use the <constant> tag when denoting constants. Constants must be written in UPPERCASE. No other content is allowed within this tag, unless a class name is used, which indicates a class constant.
<para>
The constant <constant>FOO</constant> and the class constant
<constant>Zend_Class::FOO</constant>.
</para>
Filenames and paths must be wrapped in the <filename> tag. No other content is allowed in this tag.
<para>
The filename <filename>application/Bootstrap.php</filename>.
</para>
Commands, shell scripts, and program calls must be wrapped in the <command> tag. If the command includes arguments, these should also be included within the tag.
<para>
Execute <command>zf.sh create project</command>.
</para>
