This issue came up in discussion of the APP element as well. (Dan surfs the archive...) Ah! Terry Allen crossposted something from the Java List: http://www.acl.lanl.gov/HTML_WG/html-wg-95q2.messages/1119.html *** DTD *** | | <!ELEMENT APPLET - - (PARAM*, DATA?, %flow)> | <!ATTLIST APPLET | CLASS NAME #REQUIRED -- the class name -- | NAME CDATA #IMPLIED -- the applet name -- | LANG NAME #IMPLIED -- the language name -- | SRC CDATA #IMPLIED -- source URL -- | WIDTH NUMBER #REQUIRED | HEIGHT NUMBER #REQUIRED | ALIGN (left|right|top|texttop|middle| | absmiddle|baseline|bottom|absbottom) baseline | VSPACE NUMBER #IMPLIED | HSPACE NUMBER #IMPLIED | > | | <!ELEMENT PARAM - O EMPTY> | <!ATTLIST PARAM | NAME NAME #REQUIRED -- The name of the parameter -- | VALUE CDATA #IMPLIED -- The value of the parameter -- | > | <!ELEMENT DATA - - CDATA> >The following general attributes are defined on EMBED: >SRC (required) - Specifies source URL. > >HEIGHT - The object's image will be scaled to fit the specified height >and width. > >WIDTH - The object's image will be scaled to fit the specified height >and width. OK... so now we've got: <!ATTLIST EMBED SRC CDATA #REQUIRED HEIGHT NUMBER #IMPLIED WIDTH NUMBER #IMPLIED > >NOEMBED - The EMBED container can contain a NOEMBED container, the contents of I gather this is a description of the content model of the NOEMBED element. It's not quite enough detail for me to write an ELEMENT declaration: could you sketch the content of EMBED and NOEMBED in some notation that you're familiar with, like yacc or BNF? Dan p.s. Mark Gaither: you wanna start hacking up a DTD to describe these extensions and stick it on the validation service so everybody can try them out? I know you're busy... if you're too busy, is there anybody else who runs a clone of the validation service who wants to try it out? Maybe I'll get a clone running on www.w3.org. I need to do that for the conformance testing anyway.
