040805 and earlier, 1.5.0 b62, Ocean. If you have
a line in any XML file such as

<foo name=>

the '>' will be marked in bright red as a syntax
error (unexpected token). However if you turn on
"Highlight Caret Row" in editor options for XML,
and the caret is on the same row, the '>' is
completely invisible (looks like ' ').

Disturbing when you use H.C.R. because you start
editing something like

<foo>

to insert a 'name' attr, like so

<foo name=>

or

<foo name=">

and it seems that the '>' disappears when you type
the '=', as if the KB were in overstrike mode; yet
it is really there and reappears if you type

<foo name="">

or if you just move up or down a line.
