[XeTeX] itemized list not working in XeTeX

[Brian]

Hi,

I have some documents that I want to include itemized lists.

I found a sample macro  the "Tex for the Impatient" document that  
defines how to make both numbered and unordered lists. These  
correspond to enumerate and itemize in LaTeX.

The numbered list is working correctly, with all items numbered  
correctly for their respective levels.

When I try the unordered list, XeTeX complains. The alignment of the  
items is correct, but there is no symbol on the first level of the  
list. The second and deeper levels all have the correct symbols.

If I remove the \or in front of '\or \blackbox', XeTeX runs without  
complaints, but the first level has a '---'  (the symbol for the  
second level) not a \blackbox (the first level).

I've checked the original document several times, so I don't think I  
added something or left something out.

Probably something simple I'm missing, but I can't find it.

Thanks.

Brian
