When xml schema is used, the term "schema-valid" is generally used to make
clear that no DTD is involved in the validity determination. You can avoid
the limitations by not using a DTD or schema at all, but in case you want to
be able to specify or test the structure of the document more precisely than
you can with a DTD, the various schema systems have been designed.
