In libxslt/xslt.c, the top comment of xsltParseStylesheetDoc() says:
"the doc is automatically freed when the stylesheet is closed."
Reading the code, I can confirm that xsltFreeStylesheet() does a bunch
of stuff, and that it has the idea to call xmlFreeDoc() once at the
end.
Will address this one as well. Thanks.
