Generally I agree but still I'd like to get an overview of
getElementById-Support in Browsers. If it is only NS3 lacking support of
it (which I am aware of) I don't think it needs any special care,
espacially in the TYPO3-BE (which I am pretty sure will not work in NS3).

DOM-Scripting is afaik some kind of standard, and it makes sense to cut
effort of programming in favor of a standard, that is covered by 99% of
any modern browser.

Good chance I am wrong here, so please just add one or two more voices
and I reconsider my point of view.

Cheers,
Peter
