trait SingleElementContextMatcher[+A] extends ContextMatcher[StartElement, A]
Specialization of ContextMatcher which only checks the first element in the stack for matching operations. Transformation operations on single-element matchers will yield other single-element matchers (rather than the base ContextMatcher type). Combination operations involving other single-element matchers will also yield single-element matchers. SingleElementContextMatchers form the building blocks of more complex matchers.
