DTDs - not a fixed set

Hello www-validator,

  It is common to have DTDs that declare new elements and attributes
  and then import an existing DTD. Modularization strategies from
  XHTML and SVG encourage that,and it is also common for people to
  declare their own namespaces and mix them with W3C ones so that the
  result still validates.

  It seems that the validation service will not fetch DTDs over HTTP,
  even when the full URI is given in the system identifier. This is a
  significant limitation, which should at minimum be documented
  and preferably, fixed.

  If content authors take the trouble to ensure that their own
  vertical-market namespaces are used with W3C ones in a way that is
  valid, it seems preferable to reward them rather than to
  (erroneously) declare such documents to be invalid.
