The XML recommendation says little about what the parser does.  
However, particularly in conjunction with the infoset, it is totally 
clear that the value of the attribute is a string of Unicode characters 
of length one, that character having the numeric value 955 and 
representing Unicode

U+03BB;GREEK SMALL LETTER LAMDA

A parser that passed anything other than that would be acting, uh, 
weird.
