[xsl] Quotes in a variable

["Fraser Goffin" <goffinf@xxxxxxxxxxx>]

I'm trying to create a variable that contains an XPath expression and that 
expression contains several quotes. I'm going to be outputting the value of 
this variable so I don't want to escape them with ". Is it doable ?

For example: this obviously 'barfs' because there are too many ' in the 
select attribute value :-

<xsl:variable name="anXPath" select="'//*[local-name()='MessageID' and 
namespace-uri()='http://schemas.xmlsoap.org/ws/2004/03/addressing']'"

Cheers

Fraser.
