Is this a true issue? According to W3C the id must be unique in the document, 
i.e.
two elements in the same document can't have the same id attribute.

Of course, but it's only a CSS problem.

On a website, you can have a page which contains this :
<div id="my_id" class="my_class"></div>

And another which contains this :
<div id="my_id" class="my_other_class"></div>

In your CSS file, shared with all your pages, if you write this :
#my_id{background:red;}
#my_id.my_class{background:green;}
#my_id.my_other_class{background:blue;}

The background will be red for the two pages with IE6, because you used twice 
and
directly the schema " #ID.CLASS ".

It's a little hard to explain with my poor english, sorry :)

Ah. My bad. Didn't think of that.
However, shouldn't this be a defect rather than an enhancement?

I see this bug with both of the following rules, actually:

#unique.someClass and .firstClass.secondClass

The double-class selector is where I first saw it.
