That was a lot of work, even with a map editor program. What are you trying to accomplish?

The Zone has an HTML filter based on a list of allowed tags, and MAP isn't on it. It's one of a class of tags that's a low-level security risk because script can be used in place of URLs, but unlike the A tag, which has only one URL to scrub, MAP can have an unlimited number.

Here's the list of allowed tags:
A ACRONYM ADDRESS B BGSOUND BIG BLINK BLOCKQUOTE BR CAPTION CENTER CITE COL COLGROUP DD DEL DFN DIR DL DT EM FONT H1 H2 H3 H4 H5 H6 HR I IMG INS KBD LI LISTING MARQUEE MENU NOBR OL P PRE Q RT S SAMP SMALL SPAN STRIKE STRONG SUB SUP TABLE TBODY TD TFOOT TH THEAD TR TT U UL VAR WBR

All other tags are exposed, as MAP was, by converting the angle brackets to their escaped form ('<' and '>').
