Although some Xerces versions support XMLSchema 1.1, the default
XML validation library that comes bundled with at least some java
runtime versions does not (I tried Oracle JDK 8 and OpenJDK 11,
neither worked).  Of course there's no requirement for VODML to use
a technology that's compatible with the likely capabilities of votlint.
