Ah, I obviously did not explain the issue well enough here:
The code...

exclPrefixes = xsltParseStylesheetExcludePrefix(style, cur);

...is currently processed also for every element in the XSLT namespace
(not only for literal result elements), so for...

<xsl:template match="/" exclude-result-prefixes="p">

...this should not be performed, but it is currently; actually
this attribute should be reported as invalid for xslt-elements
other than xsl:stylesheet and xsl:transform.
