Koen, I may have a partial solution to the 'long list' problem. Note that one of the features of the modular DTD format is that each module has entities declared within: 1. module version (as FPI; eg., '-//IETF//ELEMENTS HTML 2.0 Lists//EN') 2. feature negotiation keyword (eg., 'ietf-html.list-20') 3. module standards status (a text literal, one of): 'Experimental' all proprietary, unregistered or non-standards track components 'Internet-Draft' IETF standards-track components carrying an RFC number and/or registered with IANA. 'Proposed-Standard' IETF Proposed Standard 'Internet-Standard' IETF Internet Standard 4. module expiration date (matches I-D or RFC expiration date; used only as appropriate) Additionally, the DTD as a whole also declares these four entities. So for HTML 2.0 (FRC 1866) we have: 1. version: '-//IETF//ELEMENTS HTML 2.0//EN' 2. feature keyword: 'ietf-html.list-20' 3. status: 'Proposed-Standard' 4. expiration: '01-Nov-1996' So for feature negotiation, you wouldn't need to specify each and every DTD module, simply the overall DTD plus any added extensions. Adding Dave's latest tables would be (I'm guessing a bit): 1. version: '-//IETF//ELEMENTS HTML 2.0 Tables 0.6//EN' (?) 2. feature keyword: 'ietf-html.tables-06' (?) 3. status: 'Experimental' 4. expiration: '01-Mar-1997' (?)
