Well, I tested first with a stylesheet containing some
<xsl:unknown/> element and parseStylesheetDoc returned
a stylesheet object that was not None. I later found out that 
the errors where actually warnings and that libxslt 
considered the stylesheet as correct.

In the meantime, I looked at xsltproc.c and found out
that it checked the errors field in addition to checking
that xsltParseStylesheetDoc did not return null 
(around line 770), so I supposed I needed access to
that field to detect compilation errors.

Now if you tell me that it will always be None in case
of errors, that's what I need.

Btw, to get the error messages, I assume I need to use the
global error handler, since there is no "compilation
context", right?
