Randolph is perfectly right that he asks for `common' terms that describe the points Frank has brought up. (Just as Frank already uses `shortref' from the SGML realm instead inventing his own terms.) With these terms one can use the well known theory of formal languages and its processing (aka compiler construction) as a background to get more information. Just look, how Anne Brueggemann-Klein's work on categorization and complexity of SGML DTDs were able to show flaws in the basic concept. Theory and communication by common term at work. The question remains open: Do we really need context sensitive grammars to describe usual markup demands like shortrefs? Cheers, Joachim PS: Randolph, yes, the base grammar of the TeX Macro Language (TML) is context free. Of course, as with most macro language, it's an extensible grammar. (There doesn't exist a published full description of TML.) PPS: Forward the LaTeX mailing list into a local newsgroup. Then one can use KILL files, they save oneselves from reading postings by people that got too much one ones nerves. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Joachim Schrod Email: [log in to unmask] Net & Publication Consultance GmbH Tel.: +49-6074-861530 Roedermark, Germany Fax: +49-6074-861531
