********************************************************************************

    The XTM Specification will neither encourage nor
    discourage users from embarking on either of these
    courses of action.  However, the Spec will specify a
    specific URI that invoked the topicmaps.org domain name,
    to be used to specify the XTM DTD as the namespace; we
    hope this will encourage a modicum of consistency among
    topic maps that use the XTM DTD as an XML Namespace.

*** beginning of correction (addition) submitted by Sam Hunting 2000/10/24

    [no paragraph] The XTM Specification will make the
    following arrangements with regard to the use of XML
    Namespaces:

    * The root element of the of the XTM DTD will have a
      fixed -xmlns- attribute with a value that is a URI
      that references the XTM Specification.

    * In the examples found in the explanatory text of the
      XTM Specification, no namespace prefixes will appear,
      except in the first example, in which only the -xmlns-
      attribute will be explicitly and redundantly
      specified.

    * The text will state that prefixed beginning with the
      three-character sequence "xtm", in any case
      combination, are reserved for use by XTM and
      XTM-related specifications.

*** end of correction (addition) submitted by Sam Hunting 2000/10/24

    The XTM Spec will not espouse any position with respect

...

I also added clarifying language to a subsequent paragraph, which
now reads, in part:


    ... When an
    instance declares the XTM DTD as an XML Namespace, the
    DTD can still be used to validate the instance merely by
    defining the parameter entity to be a string that is the
    name as the declared XML Namespace prefix, followed by
    ":".  The Syntax Subgroup decided to recommend that, for
    the sake of human readability, the XTM DTD should not
    employ this technique; the interchange DTD will not
    include a prefix, nor will it include parameter entity
    provisions for adding prefixes.  (However, it should be
    noted that the parameter entity technique has been
    useful for those who must use XML Namespaces; it has
    been invaluable in the W3C XHTML work, and it has also
    been used in the TEI context.  The XTM Specification
    will neither promote nor deprecate the parameter entity
    technique.)
