     Of course, 'mul' and 'und' provide precisely what I was 
looking for in 'i-mixed' and 'i-unknown.' I should apologize 
for having troubled you folk with a request for something 
that was already there. The problem is that I was reading the 
old RFC1766 which is referenced from RSS V2.0 specs (via HTML 
4.0) rather than the newer RFC3066. 'mul' and 'und' aren't 
mentioned in RFC1766. And, I didn't think to look in ISO 639-
2... My apologies again. (RTFM)

    I agree with what you say here. The problem is, of 
course, that RSS V2.0 has defined its own mechanism for 
conveying information about language and, as it is clear, 
that mechanism is much less flexible than that which is 
provided by XML itself. My fear is that there are a great 
number of home-grown parsers that process RSS feeds by 
searching for complete tags and those parsers will fail if I 
start inserting xml:lang attributes...

    If only it was so easy... There are so many aggregators 
that getting them all to work properly is going to be a 
challenge. Yet, there doesn't seem to be much choice.
   Thanks for your guidance on this issue.
