---------------------------------------------------------------------
The template library textwolf implements an input iterator on
a set of XML path expressions without backward references on an
STL conforming input iterator as source. It does no buffering
or read ahead and is dedicated for stream processing of XML
for a small set of XML queries.
Stream processing in this context refers to processing the
document without buffering anything but the current result token
processed with its tag hierarchy information.
