Any idea on when a Universal enity set for XML might surface and who 
might need to be prodded/offered help to get work on it further along? 
If such a set were to be offered either before or at the same time as 
XHTML2, that would nullify that problem with &ps; and &ls;. Without it, 
I'll grant that depite any merits my idea has, this is a barrier that 
would need to be dealt with befre it could be implemented.  I'll still 
work on my survey of <p> in current web pages, so that the data is 
there to see whether it is worth trying to implement.

I never have bothered with Opera which explains why I was unaware of 
its faults. As for pre-Mozilla 1.0 Gecko-based browsers, I wouldn't 
consider their failure to support the entities a serious impediment.
(By the way, what do you mean by NCR? I'm assuming numerical entities 
such as &#8233; and &#x2029; but it isn't clear from the page.) Quite 
frankly tho, based on the reported results, since the entities are part 
of the normative specification of XHTML1, I would consider Opera to be 
non-conforming for application/xhtml+xml.

Based on my current level of understanding, I can accept a lack of 
entity support when the document is transferred as text/xml or as 
application/xml as in such a case, no claims have been made at the 
media type level that the server is providing XHTML and that the client 
understands it.
