The Saxon schema processor won't be found by the JAXP classpath search.

(Having said this, I don't generally advise people to use the JAXP 
classpath search mechanism anyway. It's very expensive, it exposes your 
application to the risk of using a schema (etc) processor that you 
haven't tested the application with, and it's very sensitive to things 
that you often have no control over, like the order of JAR files on the 
classpath).

For information, when you invoke the Saxon schema processor there is an 
option to say whether you want it to act as an XSD 1.0 or XSD 1.1 
processor. The default is currently XSD 1.0. On the command line the 
option is -xsdversion:1.0|1.1, in APIs it is the configuration property 
"http://saxon.sf.net/feature/xsd-version"; which takes the values "1.0" 
or "1.1". I'm afraid it never occurred to me to use a 37-character 
string for the property value.
