You can have nested declarations -- an xs:element holding an anonymous
xs:complexType that contains xs:elements.

You can also have xs:group definitions at the top level that hold
model groups.

And xs:complexTypes themselves can contain
xs:complexContent/xs:restriction or xs:complexContent/xs:extension
elements, which then hold the content models.

And the content model elements xs:choice/xs:sequence can be nested
inside each other. Plus there's xs:all.

If you're searching for element declarations or references in all
those places, and you're doing it multiple times, all in all it's a
lot easier to create a key:

<xsl:key name="elements" match="xs:element" use="(@name | @ref)" />

Then you can just do:

  key('elements', $node_name)

rather than constructing a massive path. It'll be quicker too.

Cheers,

Jeni
