Here is a schema generated from the DTD for JNLP 6.
It looks similar to XSD, but not quite. What is it?

It *is* XSD. However, the DTD->XSD translation has (sensibly enough)
translated all the <!ELEMENT DTD components into top-level <element>
components in the schema, resulting in a schema with many anonymous
complex types and many top-level elements, which is unusual (IME).
A more idiomatic translation would have many named complex types and
one or a very few top-level elements. This schema allows for, eg., a
document composed only of
<param name="x" value="y" />
to be valid.
