Please allow me to disagree, at least on definition...

The ampersand character (&) and the left angle bracket (<)
MUST NOT appear
in their literal form, except when used as markup delimiters, or
within a
comment, a
processing
instruction, or a
CDATA section.
If they are needed elsewhere, they
MUST be
escaped
using either
numeric character references
or the strings "
&
" and "
<
"
respectively. The right angle bracket (>)
may be represented using the string "
>
",
and
MUST,
for compatibility, be escaped
using either "
>
" or a character reference when it
appears in the string "
]]>
" in content, when
that string is not marking the end of a
CDATA
section.

So in any XML document (i.e. OSM data), it MUST be escaped to be valid XML. As I mentioned, it does not break mkgmap so it is not a big issue...
In the meantime, I have worked around it by better tracking quotes. I just reported what I think it is a possible bug...
Thank you,
