I don't think that, using an "if" (xsl:if / xsl:choose in XSLT, "if" in
XPath) control flow mechanism in the code (and equally well in XSLT) is
always a bad idea. It's an integral programming tool to solve problems. To
have code look nicer, may be we can encapsulate the "if" logic within a
function.
