Default HTML 4.0 stylesheet in CSS2/CSS2.1

The sample default stylesheet for HTML 4.0 in CSS2 (and CSS2.1) contain an
equivalent to the following:

ol { list-style-type: decimal }

As 'list-style-type' is inherited (as it should be) ul elements within ol
elements ends up with the "wrong" style.

I suggest adding

ul { list-style-type: disc }

to the sample default stylesheet for HTML4.0. Alternately we could add

ol > li > ul { list-style-type: disc }
