I tried it and repeating quotes works. The XPath expression would be unescaped:
//document[path="/rootNode[itg:fts(.,' ""information to
I didn't know you could repeat quotes like that in an XPath expression. Is this in the spec? Well, yes it is. It's in the XPath 2.0 Recommendation: http://www.w3.org/TR/xpath20/#id-literals
I just learned something new. Thanks for pointing me to this new trick.
