And it was even easier to take the FXSL JSON-to-XML conversion/parsing
utility that I was able to turn it into a Saxon on .NET-drive web
service[1,2] in about 5 minutes.

Such is the power of using well designed languages, language processors,
and associated extension libraries.

NOTE: I still need to write a proper query-string parser to specify
whether a query-string variable belongs to the service end point or a URI
specfied as a query string variable, so at the moment the query string
variables are hard coded into this demo.  But that is a specific issue
associated with using URI's, HTTP GET and query string variables, not with
XSLT 2.0/Saxon on .NET/FXSL.  You could just as easily use an XML payload
via either GET or POST and avoid tbis specific issue all together.
