First, for each XML file within the "repo" folder create an acompaning file with a ".meta" extension like the "step4" example is doing:
<?xml version="1.0" encoding="UTF-8"?> <metapage> <author>me</author> <category>catb</category> <state>edited</state> </metapage>
Add 2 additional match nodes to your pipeline:
<map:match pattern="page/**">
<map:aggregate element="aggregation" label="content">
<map:part src="cocoon:/raw/{1}"/>
<map:part src="cocoon:/meta/{1}"/>
</map:aggregate>
<map:serialize type="xml"/>
</map:match>
<map:match pattern="meta/**">
<map:generate src="{global:staging}repo/{1}.meta"/>
<map:serialize type="xml"/>
</map:match>
Now create 2 additional files within the "authentic" folder, aggregation.xsd (the XML schema)
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
<xs:element name="aggregation">
<xs:complexType>
<xs:sequence>
<xs:element ref="page" minOccurs="1" maxOccurs="1"/>
<xs:element ref="metapage" minOccurs="1" maxOccurs="1"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="page">
<xs:complexType>
<xs:sequence>
<xs:element ref="title"/>
<xs:element ref="content"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="content">
<xs:complexType>
<xs:sequence>
<xs:element ref="para" maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="title" type="xs:string"/>
<xs:element name="para">
<xs:complexType mixed="true">
<xs:sequence minOccurs="0" maxOccurs="unbounded">
<xs:element ref="emphasis" minOccurs="0" maxOccurs="unbounded"/>
<xs:element ref="image" minOccurs="0" maxOccurs="unbounded"/>
<xs:element ref="link" minOccurs="0" maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="emphasis">
<xs:complexType mixed="true"/>
</xs:element>
<xs:element name="image">
<xs:complexType>
<xs:attribute name="href" type="xs:string" use="required"/>
<xs:attribute name="height" type="xs:long"/>
<xs:attribute name="width" type="xs:long"/>
</xs:complexType>
</xs:element>
<xs:element name="link">
<xs:complexType mixed="true">
<xs:attribute name="href" type="xs:string" use="required"/>
</xs:complexType>
</xs:element>
<xs:element name="metapage">
<xs:complexType>
<xs:sequence>
<xs:element ref="author" minOccurs="1" maxOccurs="1"/>
<xs:element ref="category" minOccurs="1" maxOccurs="1"/>
<xs:element ref="state" minOccurs="1" maxOccurs="1"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="author" type="xs:string"/>
<xs:element name="category" type="xs:string"/>
<xs:element name="state" type="xs:string"/>
</xs:schema>
and aggregation.sps (the authetic-specific stylesheet)
<?xml version="1.0" encoding="UTF-8"?>
<structure version="2" schemafile="aggregation.xsd" workingxmlfile="" templatexmlfile="">
<nspair prefix="xs" uri="http://www.w3.org/2001/XMLSchema"/>

<match overwrittenxslmatch="/"/>
<children>

</structure>
Now change your "file2html.xsl" stylesheet to reference these files instead of "content.xsd" and "content.sps".
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:param name="file"></xsl:param>
<xsl:param name="sitemapURI"></xsl:param>
<xsl:param name="requestURI"></xsl:param>
<xsl:param name="serverName"></xsl:param>
<xsl:param name="serverPort"></xsl:param>
<xsl:template match="/page">
<html>
<body>
<OBJECT id="objPlugIn"

<PARAM NAME="EntryHelpersEnabled" VALUE="TRUE"/>

</OBJECT>
<br/>
<input type="button" name="submit1" value="Save" onClick="objPlugIn.SavePOST()"/>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
Now you already can edit your meta data together with your XML document. Adjust your "stream2write.xsl" stylesheet to separate the data and metadata down the pipeline again:
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:req="http://apache.org/cocoon/request/2.0"
xmlns:source="http://apache.org/cocoon/source/1.0">
<xsl:param name="file"></xsl:param>
<xsl:template match="/aggregation">
<page>
<xsl:apply-templates/>
</page>
</xsl:template>
<xsl:template match="page">
<source:write create="true">
<source:source><xsl:value-of select="$file"/></source:source>
<source:fragment>
<xsl:copy-of select="."/>
</source:fragment>
</source:write>
</xsl:template>
<xsl:template match="metapage">
<source:write create="true">
<source:source><xsl:value-of select="$file"/>.meta</source:source>
<source:fragment>
<xsl:copy-of select="."/>
</source:fragment>
</source:write>
</xsl:template>
</xsl:stylesheet>
Adjust your sitemap to exclude your ".meta" files from folder traversal like the "step4" sample is doing.
