[xml] libxslt does not check extension function existence at creating stylesheet time

[ajay bhadauria <abhadauria yahoo com>]

Hello,

 

We are compiling stylesheet which has dependent xslt files  through import. These dependent xslt files have extension functions.

We noticed at stylesheet creation time , libxslt does not check on the existence of the extension functions. However, at validation time

when we apply the stylesheet , we get the error indicating that the extension function is not found.

 

We register the extension functions through xsltRegisterExtModuleFunction() providing the correct namespace and callbacks.

 

Could you please help us

 

1.  Why it does not complain extension function during stylesheet creation ?

2. Why it is not finding function at validation time ?

 

 

Regards

Ajay
