Curly braces are never used within an XPath expression: they are only used
when an XPath expression is embedded in text within an attribute value

In standard XSLT, you can't construct an XPath expression dynamically from a
string, or interpret an XPath expression held in a source document. However,
Saxon (and some other products) have an extension to do this:


(This is Saxon 8.4)

(You'll see saxon:evaluate() more often than saxon:evaluate-node(). The main
difference is that evaluate-node() takes namespace prefixes from the
namespace context in the source document, not from the namespace context in
the stylesheet.)
