I have seen the way and worked a little with how AdoDB solves that problem using
there Adodb-xmlschema and that looks very promising. This will make the DBAL
extreemly portable so the typo3 (extention)developers do not need to focus on
'will the SQL convert right to <name a RDMBS>'. 

Also all new extentions can be made pluggable that way. The schema allows you to
add/remove columns on the fly to which is what typo3 needs on some extentions.

This ofcourse will limit typo3 to and will only support what adodb will support
 on there backend.
