[XML-SIG] XSV string length checking

[Andrew Maclean]

Dear All,

I've come across an error running XSV and I was wondering if I could have an 
opinion.  Basically, it doesn't seem to enforce restrictions on the length 
of string values.

The output tells me that it's being "strict", but I put supply a zero-length 
string in the test xml file.

Below are the source XSD, XML and output files:

Other checks work, and I get the "element content failed type check..." if I 
try and put something strange into the <WFDAssessment> tag.  String lengths 
aren't being checked though.
Thank you,

Mr Andrew Maclean
