I have seen it very frequently in CMS-generated pages. IMNSHE it is the
result of an automated process embedding the CSS information, and
deliberately double-shielding it because at some dim, distant stage in
the past, a developer was told that XML processing "couldn't handle"
less-thans and ampersands, and the best thing to do was to wrap the CSS
in as many layers of protection as possible.
