For some reason it is defined as \lbracket in MkIV and undefined in MkII. Does anyone use \lbracket? If not, we can change it to \lbrack. Otherwise, we can also have both \lbrack and \lbracket defined. Any thoughts? Aditya

Any thoughts? Either both or the long form only, memory is no longer a reason to create funny names like \infty (can we add \infinity please)

I strongly disagree with the idea not defining the forms \lbrack and \lbrace. Fact is that Knuth defined them in the base of TeX's math. We should at least stay compatible with that. And please do not also kill \infty. Why then not also change \equiv to \equivalent, \approx to \approximate etc, etc? If we start diverging in that way, we loose all ground. To me that sounds as a horror scenario. Hans van der Meer

Good. I have absolute no objection to adding \infinity as an extra to \infty. However, I would plea for a process whereby can be determined which names to add. Will it for example be \infinity? Or do we choose \infinite? Otherwise it might lead to a plethora of nearly similar names for all those Knuth'ian short names. Hans van der Meer

If you want to have a process for debating names, then I do not think that the list in char-def is every going to be 10% full. Even right now, we have not been able to add all the existing short names. As a start, I think that we should support all full names in mathml. Someone has already gone through the painful process of having a consensus on the symbol names, so lets just use that. We can worry about the more "obscure" symbols later.
Will it for example be \infinity? Or do we choose \infinite?
In this case, the choice is easy. The symbol has only one name: infinity. Mathml has an entity called infinity. I have not heard it being called infinite.
Otherwise it might lead to a plethora of nearly similar names for all those Knuth'ian short names.
I agree. But I doubt that having a debate about the full name of the symbol is going to help. Different fields use different names for the same symbol. Knuth short names are not perfect to being with. My personal favorites being \cap and \cup for \intersection and \union. Aditya

actually i'd like \mathequivalent as core command and then we can have \eq as shortcut (just as we have \eacute etc) ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

That sounds good. Do you want the shortcuts to be defined in char-def or someplace else? Aditya

i'll change it to lbrack + rbrack ... indeed we should use mml names in char-def and then have a list of equivalents but it has a low priority Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
