[xsl] RE: output/@indent="yes" and *[@xml:space="preserve"]

["Michael Kay" <michael.h.kay@xxxxxxxxxxxx>]

Oh dear, I think you're right. The spec says in effect that whitespace
shouldn't be added where <xsl:strip-space> wouldn't cause it to be
stripped: which is the case when xml:space="preserve" applies. It also
says that it shouldn't be added inside an xsl:text element - a rather
odd provision which seems to special-case the output of stylesheets.
