[xslt] An Invalid xpath expression xsl:template/@match node is ignored

[Nicolas Delaby <nicolas deliveryhero com>]

Dear libxslt maintainers,
I discover that performing a transformation with a invalid xpath 
expression in a template match attribute doesn't prevent the 
transformation to perform and lead to compromise the transformation logic.
Instead, I would expect to have a proper failure like `could not compile 
match expression`

I attached a stylesheet and xml sample to reproduce the issue.

result of transformation:

$ xsltproc xpath-typo.xsl document.xml
error: file xpath-typo.xsl line 10 element template
xsltCompilePattern : NULL pattern
<?xml version="1.0"?>
<result><bug/><bug/></result>
$ echo $?
0


version I'm currently using:

$ xsltproc --version
Using libxml 20708, libxslt 10126 and libexslt 815
xsltproc was compiled against libxml 20708, libxslt 10126 and libexslt 815
libxslt 10126 was compiled against libxml 20708
libexslt 815 was compiled against libxml 20708


Is it a bug ? Should I open a ticket in bug tracker ?

Thanks,

Nicolas
