RE: [xsl] xslt2 complex content sequences

Saxon compiles this XQuery into code equivalent to:

<xsl:element name="a">
 <xsl:sequence select="1,2"/>
 <xsl:text/>
 <xsl:sequence select="3"/>
</xsl:element>

The zero-length text node disappears when added to an element, but it stops
the 2 and 3 being considered adjacent.

You could of course convert all the values to text nodes "by hand" using
xsl:value-of, which would eliminate all automatic spacing. That would seem
more natural in XSLT.
