Processing instructions
A description of the processing instructions you may use in Content Editor
Processing instructions are used to embed different types of information. They are XML nodes with the opening a closing tags with a question mark (
?) that look like this:
<?name content?>
Processing instructions cannot be nested.
xml and XML are reserved names for XML version 1.0 and onwards.
For example, most XML documents should start with a special processing instruction called the "prolog":
<?xml version="1.0" encoding="UTF-8"?>
Another standard processing instruction can be used when you want to put a reference to your XSL transforms (stylesheet) in an XML document:
<?xml-stylesheet type="text/xsl" href="[pathToXSLStylesheet.xslt]"?>
Other names are for Content Editor -specific processing instructions
For example processing instructions are used for storing change tracking information:
<?xm-deletion_mark author='John Doe' time='20090519T153330+0000' data='users'?>
