RE: HTML tags to be filtered out

[le]

Like a good firewall layout, it could be easier to define what's allowed, not what's forbidden.

My vote is for B, I, OL, UL, LI, A (although this could be a hole too), HR, BR, P; maybe IMG, maybe Hx, maybe PRE and maybe TT.

[turnstep]

Well, since we've started the "Allowed" list already, I'll add my $0.02, and rearrange the list from what I see as the least to most controversial:

• CODE (of course)
• STRONG, EM, B, I
• BR, P
• <!-- (comments - take a look, you might be surprised at what is already there!)
• UL, OL, LI, MENU
• DL, DT, DD (well, I still use them anyway)
• BLOCKQUOTE (I use this often actually)
• TT, ADDRESS
• PRE (perlmonk's code does not always cut it)
• SUB, SUP
• A
• DIV
• HR

Almost all of them should require a matching close code as well.
