I wanted to be quite clear that

<xsl:function name="increment">
   <xsl:param name="x"/>
   <a/>
   <xsl:return select="$x+1"/>
</xsl:function>

is an error, and I felt it would be harder to state this clearly and give
clear error messages if <xsl:function> and <xsl:template> were coalesced
into a single construct.

I think it's better that this should be an error than that the <a/> element
is written to some "black hole" output destination. Certainly, <a/>
shouldn't be written to the final result tree, which it would be in a
template called using xsl:call-template.
