RE: [xsl] A non self closed xsl:apply-templates element to create a text node for matching ...

["Michael Kay" <mike@xxxxxxxxxxxx>]

It's not legal to have an xsl:value-of element as a child of
xsl:apply-templates, and I'm really not sure what you would expect it to
mean.

I can't see the difficulty in having a single template rule that matches
both text nodes and attribute nodes, for example

<xsl:template match="text() | @*">

perhaps with appropriate filters and/or a special mode.
