Integer validation in WSDL2C.sh generated code

[slowpoison]

I noticed that there is no validation for integers in the generated
code. For example if I define by integer to be of type
positiveInteger, the code won't check that it's zero.

I'm wondering if there is a way to do this.
If not, I'd like to know how easy/hard will it be to add it. I'm
willing to spend some time to write a patch for that. Just sizing up
the effort first.

thanks!
