[xslt] Return of xsltApplyStylesheet

[Eric van der Vlist <vdv dyomedea com>]

I am confused about the return value of xsltApplyStylesheet when there 
is an error.

I have tried to generate a stylesheet run time error by using the 
document() function on a non existing document and by using an undefined 
extension namespace. In both cases, a non NULL value has been returned 
by xsltApplyStylesheet.

Are such failures considered as warning and, if yes, how can I trap them?

Thanks

Eric
