Inconsistent SAX parser behaviour: UNICODE CHARACTER REFERENCES & ENTITIES ?

Hi,

I have been experimenting with entities and character references and 
have now reached a state of total confusion. 

According to my knowledge about ENTITIES and character references the 
subtle but important difference between the two is that the parser (is 
supposed to) expand character references immediately. 

Thus, writing ' " ' or '"' would not be identical, since the latter 
is an entity and is not expanded at parse-time,

whereas writing ' " ' or '"' should have the same effect since the 
latter is a character reference and thus should be expanded at 
parse-time. 

Following, this logic if I have a 3 elements in my XML file

1) <foo   name="A&quot;B"> ... </foo> 
2) <foo   name="A&x34;B"> ... </foo> 
3) <foo   name="A"B"> ... </foo> 

the first should be parsed okay while the last two should give me a 
parser error. However, I find that the first TWO are parsed okay while 
the third results in a parse error. The SAX parser implementation I am 
using is CRIMSON.

It is essential for my application to deal with these occurences of 
unicode character references and entities. Things are getting a bit 
complicated now that I figured out that the parser does not behave as 
expected.

I would greatly appreciate if someone could shed some light on this.

THANKS !!!!

     Stefan
