After looking at the schema, it seems that the problem is not the
<any> wildcard: you need to validate with XSI-driven schema assembling.
The schema uses xsi:schemaLocation to load schemata dynamically when
needed. This is currently not accessibly via xmllint [2].
But you'll find an example at [1] about how do it otherwise -
Daniel did not add it to the code examples yet ;-)
If you need to use xmllint, you can create one additional schema,
<import> all other schemata and validate against this new schema.

In you lucky case the "##other" bug does not do any harm.

Would be happy about a feedback here.
