XFML DTD
Date: Thu, 06 Jun 2002 18:56:16 -0400 From: PeterV <peter@poorbuthappy.com> To: xfml@yahoogroups.com Subject: XFML DTD
Here is a new version of the DTD, comments welcome. Note that I added
<occurrencetypename>, <topicname> and other such elements. That seemed the
best way but correct me if I'm wrong.
<!ELEMENT xfml (occurrencetype | publisher | facet | topic | page)*>
<!ATTLIST xfml
url CDATA #IMPLIED
version CDATA #REQUIRED
copyright CDATA #IMPLIED
language CDATA #IMPLIED
>
<!ELEMENT publisher (name, ordername?, url?)>
<!ELEMENT occurrencetype (name, ordername?)>
<!ELEMENT facet (name, ordername?)>
<!ELEMENT topic (name, ordername?, facetname, parent?, merge*)>
<!ELEMENT merge (#PCDATA)>
<!ELEMENT parent (#PCDATA)>
<!ELEMENT page (name, url, ordername?, publishdate?, publishername*,
occurrence*)>
<!ELEMENT occurrence (topicname, occurrencetypename?)>
<!ELEMENT publishdate (#PCDATA)>
<!ELEMENT name (#PCDATA)>
<!ELEMENT ordername (#PCDATA)>
<!ELEMENT url (#PCDATA)>
<!ELEMENT facetname (#PCDATA)>
<!ELEMENT topicname (#PCDATA)>
<!ELEMENT publishername (#PCDATA)>
<!ELEMENT occurrencetypename (#PCDATA)>
Here is a validating XFML file using the above DTD:
