XML Catalog issue 22

[John Cowan <jcowan@reutershealth.com>]

# Do we want to create a TR9401 namespace to handle all of TR9401
# in our XML catalog.

Here is a preliminary proposal:

The following elements belong to the <insert namespace here> namespace,
which is referred to in the following examples with the sgml: prefix.
Of course, any prefix may be used.  These elements are not part of
the XML Catalog standard, but are provided for the convenience of
those who wish to round-trip TR9401-conformant catalogs to and
from XML Catalog format.  They allow the entries which are not
translatable to XML Catalog entries to be included within the
XML Catalog.

Note that in any such round-trip conversion, storage object identifiers
must be converted to and from URIs.  This may not always be
possible.


The sgml:sgmldecl Entry

The sgml:sgmldecl element associates a URI with an SGML declaration,
and corresponds to an SGMLDECL entry in a TR 9401 catalog.

<sgml:sgmldecl
   id = id
   uri = uri-reference
   xml:base = uri-reference />


The sgml:document Element

The sgml:document element associates a URI with a document entity,
and corresponds to a DOCUMENT entry in a TR 9401 catalog.

<sgml:document
id = id
uri = uri-reference
xml:base = uri-reference />


The sgml:entity Element

The sgml:entity element associates a URI with an entity which has
a specified name, and corresponds to a ENTITY entry in a TR 9401
catalog.

<sgml:entity
   id = id
   name = entity-name
   uri = uri-reference
   xml:base = uri-reference />

An sgml:entity entry matches an entity if the name of the entity is
lexically identical to the normalized value of the name attribute
of the entry.


The sgml:doctype Element

The sgml:doctype element associates a URI with the replacement text
of a doctype declaration which has a specified document type name, and
corresponds to a DOCTYPE entry in a TR 9401 catalog.

<sgml:doctype
id = id
name = doctype-name
uri = uri-reference
xml:base = uri-reference />

An sgml:doctype entry matches an entity if the name of a document type
is lexically identical to the normalized value of the name attribute
of the entry.


The sgml:linktype Element

The sgml:linktype element associates a URI with the replacement text
of a linktype declaration which has a specified link type name, and
corresponds to a LINKTYPE entry in a TR 9401 catalog.

<sgml:linktype
id = id
name = linktype-name
uri = uri-reference
xml:base = uri-reference />

An sgml:linktype entry matches an entity if the name of a link type
is lexically identical to the normalized value of the name attribute
of the entry.


The sgml:notation Element

The sgml:notation element associates a URI with an entity which has
a specified name, and corresponds to a NOTATION entry in a TR 9401
catalog.

<sgml:notation
id = id
name = notation-name
uri = uri-reference
xml:base = uri-reference />

An sgml:entity entry matches a notation if the name of the notation is
lexically identical to the normalized value of the name attribute
of the entry.


The sgml:dtddecl Element

The sgml:dtddecl element associates a URI with a public identifier that
refers to a DTD, and corresponds to a NOTATION entry in a TR 9401
catalog.

<sgml:dtddecl
   id = id
   publicId = public-identifier
   uri = uri-reference
   xml:base = uri-reference />

An sgml:dtddecl entry matches a DTD if the normalized value of the
public identifier is lexically identical  with the the normalized value
of the publicIdStartString attribute of the entry.
