Contains renderers and parsers for both XML and HTML 5 document fragments,
which share data structures wo that it's easy to work with both.  Document
fragments are bits of documents, which are not constrained by some of the
high-level structure rules (in particular, they may contain more than one
root element).

Note that this is not a compliant HTML 5 parser.  Rather, it is a parser for
HTML 5 compliant documents.  It does not implement the HTML 5 parsing algorithm,
and should generally be expected to perform correctly only on documents that
you trust to conform to HTML 5.  This is not a suitable library for implementing
web crawlers or other software that will be exposed to documents from outside
sources.  The result is also not the HTML 5 node structure, but rather something
closer to the physical structure.  For example, omitted start tags are not
inserted (and so, their corresponding end tags must also be omitted).
