SPAN CLASS ID, ID stripped

Hi,

I got a piece of HTML looking as follows:

<span class="areaheader" id="middle">WELCOME!</span>

Both the class and the id are important for CSS formatting. However,
XMLC generated HTML does not contain the "id=middle" so the formatting
is incorrect.

Any idea why XMLC strips out the "id" from "<span>"? Any way how to
preserve the "id" there? Or a workaround for this problem?

I am using Enhydra 5.0+, SUN JDK 1.4.1, JBuilder 7.
