Which schema? Here's what I understand you to be describing:
<xs:schema targetNamespace="urn:s:1" xmlns:s1="urn:s:1">
. . .
. . .
<xs:schema targetNamespace="urn:s:2" xmlns:s1="urn:s:1">
<xs:element name="alt" substitutionGroup="s1:head">...</xs:element>
xsi:schemaLocation="urn:s:1 s1.xsd urn:s:2 s2.xsd"

I'm not sure I'm answering your question, but the above is the minimum
necessary, and is schema-valid.

What processor is that? Please unpack the acronym.
