RE: web.xml layout
Hmm... correct me where I may be wrong, please. If the xml doc doesn't conform to the DTD, it is not 'valid' xml. But, so long as it is 'well formed' the parser will accept it just the same. The parser may look to the DTD for a parsing structure, but the callback utilization of SAX (assuming Tomcat uses SAX to parse web.xml) will negate any need to have a 'valid' -- as opposed to 'well formed' -- xml document. And that is the crux of my question. Does it really matter whether web.xml is 'valid' or simply 'well formed'?

Great! Thanks for the link, and cudos to Mike Slinn et.al. for the good work.

RE: web.xml layout
I believe that the web.xml is parsed using the DTD, so rearranging the elements will make it complain that the format of the file is incorrect. Even if you find a container which lets you rearrange, the spec says you should follow the DTD. So to be portable . . . .
