embedding xsd/xslt in XML

I want to include the xsd scheme of my xml in the document itself, like in
the ado xml-recordset. (ex: http://www.vbxml.com/xsl/articles/xsl_ado/) In
xml spy it doesn’t validate, the error is that he can't find the scheme. Is
there something wrong with my XML, or is it just xml spy?

I have the same problem with including xslt in xml , it has something to do
that I have to include the following dtd???
<!DOCTYPE doc [<!ATTLIST xsl:stylesheet id ID #REQUIRED >]>

This is my document:

<xml xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="#CMODataSchema">
