-  This class provides some basic amenities for parsing protocol XML of
-  the kind we use in the RPKI protocols, including whacking all the
-  protocol element text into US-ASCII, simplifying accumulation of
-  text fields, and hiding some of the fun relating to XML namespaces.
-
-  General assumption: by the time this parsing code gets invoked, the
-  XML has already passed RelaxNG validation, so we only have to check
-  for errors that the schema can't catch, and we don't have to play as
-  many XML namespace games.
