The normal approach is to use nested grammars. Something like this:

<grammar xmlns="http://relaxng.org/ns/structure/1.0"/>

  <include href="xhtml1-strict.rng" ns="http://www.w3.org/1999/xhtml"/>

  <define name="misc.inline" combine="choice">
    <grammar>
      <start>
	<ref name="math"/>
      </start>
      <include href="mathml2.rng" ns="http://www.w3.org/1998/Math/MathML"/>
    </grammar>
  </define>

  <define name="misc.inline" combine="choice">
    <grammar>
      <start>
	<ref name="svg"/>
      </start>
      <include href="svg10.rng" ns="http://www.w3.org/2000/svg"/>
    </grammar>
  </define>

</grammar>
