Sure. From the OP I couldn't get a firm impression if he wanted to
have the root node matched by a match pattern -- he never used this
term -- or selected by any XPath expression. Therefore I tried to
answer both questions.

I gave  ancestor::node as an example of an XPath expression that
matches the root node, not as an example of a match pattern. Probably
we need a more strict terminology in order to distinguish between
these two important cases.

It is good to have such questions that help emphasize the difference
between XPath expressions and match patterns.
