Don't organize a list in an unstructured manner, like this:
- Instruments found within the string section of a symphony orchestra:
- Violins
- Violas
- Cellos
<UL>
<LI>Instruments found within the string section of a symphony orchestra:
<DL>
<DT>Violins
<DT>Violas
<DT>Cellos
</DL></UL>
This list was created with the DL and DT elements, which should be used for definition lists, not simply for indenting a list. Instead, use the unordered list element <UL> if this is really a list, or use CSS if all you want is the indentation provided by <DL>, for example:
<P style="text-indent: 3em">Violins</P>
will indent an item without adding any unwanted semantics to the markup.
