No, it is an XPath expression, consisting of a single function call. I
think that the terminology confusion comes because XPath sounds as
though it's just about paths, but actually location paths are just one
type of expression (albeit the most common). Expressions cover
anything that you can put in the select attribute of xsl:value-of, so
include arithmetic and function calls.

Most functions, including concat(), are defined as part of XPath;
there are only a handful of functions defined in XSLT, like
format-number() and document().

Cheers,
