Saxon

I'm hitting a number of issues trying to run this.

(A) It ought to be possible to specify

com.saxonica.Validate -u http://some.domain/source,xml

supplying the source document to be validated positionally. But this is failing with an NPE. We attempt to resolve the URI using the catalog URI resolver, which returns null, and then we don't make a further attempt using the direct resolver. Fixed this (Validate.java line 604).

If I instead try to supply the source document using -s:http://some.domain/source,xml then (on Mac) it tries to treat this as a colon-separated list of source documents (colon being the platform delimiter for filenames. I think that when -u is specified, we should assume the parameter is a single URI, not a list.

First step: for both the source document and schema document, if -u is specified or if the name given is an "implicit URI" (starts with http:. https:, or file:), then the request to resolve the URI includes the DirectResourceResolver as well as the catalog resource resolver. This allows a schema document or source document specified positionally to be resolved.

Second change: if -u is specified with -s, then the list of URIs in the -s option is space-separated rather than colon or semicolon separated (if more than one appears, the list will have to be in quotes).

Third change: currently the names in the -xsd option must be separated by semicolons (regardless of platform). Change this to use the same logic as the -s option: semicolon on Windows, colon on Mac and Linux, whitespace if -u is specified.

For compatibility, because the current code here is working as described in the documentation, make this change only on the 12.x branch.
