First, suppose that we already have a schema
fragment for HTML-in-XML.  The root element
type is html.  Its URL is:

URL: http://www.w3.org/html-xml.schm

Assume that this schema provides a
substitution variable, say exp.   exp appears 
in content models

Second, suppose another schema for MathML.
The root element type is mathexp.  Its URL is:

URL: http://www.w3.org/mathml.schm

Then, we can easily combine the two fragments 
as below:

<!--  Namespace declarations  -->

<!XML:namespace HTML-XML href = "http://www.w3.org/html-xml.schm">
<!XML:namespace MathML   href = "http://www.w3.org/mathml.schm">

<!--  Schema Composition -->

<composite_schema at="HTML-XML:exp">
  <atomic_schema namespace="HTML-XML" root = "html">
  <atomic_schema namespace="MathML" root = "mathexp">
</composite_schema>

I came from the Principles of Digital Document Processing community.  
I presented my work there two years ago and going to present a database 
language there this month.  See http://www.irisa.fr/ep98
