+<?xml version="1.0"?>
+<!--
+	A combination of Mozilla's textarea, timed-textbox, input-box, and
+	input-box-spell bindings, with the timed-textbox's Return key
+	event handler removed
+	
+	Note: It would be much nicer if a) Mozilla offered this natively or
+	b) we just extended the timed-textbox binding directly, but since it's based
+	on html:input rather than html:textarea, doing so breaks things in various
+	ways (though it may be possible with some tweaking)
+	
+	Also note: spellcheck code here is a slightly adjusted version
+	of a patch by Neil Deakin on Bugzilla that wasn't 	approved in time for
+	Firefox 2.0 (https://bugzilla.mozilla.org/show_bug.cgi?id=346787).
+	When there's native support for spellcheck="true" in XUL,	we'll hopefully be
+	able to use that, though it'll still need to work as a timed textarea...
