Microsoft XML - any (<xs:any namespace="##any"/>)

any (<xs:any namespace="##any"/>)

I have this schema:

<xs:element name="MyElement">
<xs:complexType>
<xs:sequence>
<xs:any namespace="##any"/>
</xs:sequence>
<xs:attribute name="Id" type="xs:ID" use="required"/>
</xs:complexType>
</xs:element>

well, the problem is that validation of this fails:

<MyElement>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0" xmlns:xdb="http://xmlns.oracle.com/xdb"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
</MyElement>

Why? What should I use instead of ##any?

There are 3 problems here.
One is that your document that you try to validate is not XML as it is
not wellformed, you need to close the xsl:stylesheet element to have it
well formed.

<MyElement>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0" xmlns:xdb="http://xmlns.oracle.com/xdb"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/>
</MyElement>

The second problems is that xs:any contains an attribute
processContents that can have 3 possible values: strict, lax and skip.
By default its value is strict and that means that a schema for the
elements matched by xs:any must be provided. If you set its value to
lax or skip the xsl:stylesheet element will be accepted by the xs:any
wildcard.

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

<xs:element name="MyElement">
<xs:complexType>
<xs:sequence>
<xs:any namespace="##any" processContents="lax"/>
</xs:sequence>
<xs:attribute name="Id" type="xs:ID" use="required"/>
</xs:complexType>
</xs:element>
</xs:schema>

The third problem is that your schema specified the Id attribute for
the MyElement as Required so your document is not valid, to have it
valid you either need to add the attribute in the instance document and
change the schema to not require that attribute.

Here there is a valid instance against the above schema:
<MyElement Id="e1">
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0" xmlns:xdb="http://xmlns.oracle.com/xdb"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/>
</MyElement>

Is there XML Schema describing XSL ("xsl:stylesheet" and other XSL
elements).

I just replied you on the "XML Schema for XSL(T)?" thread.
