  I have reread the specific section in the XSLT-1.0 spec. It seems
that the attribute of the xsl:output element should not influence
any of the compilation steps, so modifying those specific element 
should not generate incoherencies. There is no API for it but at least
this sounds safe. If you have a good API to suggest, do so,
