[xslt] Patch: rng stream validation (Bug 512454)

[Noam Postavsky <npostavs users sourceforge net>]

Hi,

I think the problem is that the return value of xmlRegexpIsDeterminist()
is ignored. The patch fixes the test cases mentioned in the report[1],
but I don't entirely understand what the functions do so I'm not sure
whether my patch is correct.

thanks, Noam
