A NodeTest is a simple kind of pattern that enables a context-free test of whether
a node has a particular
name. There are five kinds of name test: a full name test, a prefix test, and an
"any node of a given type" test, an "any node of any type" test, and a "no nodes"
test (used, e.g. for "@comment()")
