That book is wrong.  In HTML 4, the content model of the UL element
is defined as follows, in all DTDs (Strict/Transitional/Frameset).

    <!ELEMENT UL - - (LI)+                 -- unordered list -->

So you have to write something like this:

	<UL>
		<LI>stuff
		<UL>
			<LI>even more stuff</LI>
		</UL></LI>
	</UL>

The reason is exactly what the validator said.  OL is a block-level
element, and not allowed in B, which is an inline-level element.

Use style sheets to control presentation, e.g. the following rule

   OL { font-weight: bolder }

will make an entire list boldface.
