Hi,
lets say, that somewhere in an XSLT context, I want to do this:

<xsl:sequence select="<my-cool-element>foo</m-cool-element>" />

But that is too insane, so I rewrite it like this:

<xsl:sequence select="element my-cool-element { 'foo' }" />

Only if constructors were supported in XPath.
But I CAN create new nodes in XSLT context!
So I end up with:

<xsl:function name="my:const-my-cool-element" as="element()">
  <const-my-cool-element>foo</const-my-cool-element>
</xsl:function>
.
<xsl:sequence select="my:const-my-cool-element()" />

Yay :(
There is no question, really.

Jakub.
