Here are some potential compatibility issues with respect to RFC 4514 
and RFC 2253. These are based on the grammars of section 3 in each RFC.
1. 4514 allows attribute type keywords to be of length 1, whereas 2253 
requires them to be at least length 2.
I think this is a bug in the grammar of RFC 2253, and any 
implementations that enforce a length of 2 cannot really be usable. For 
example, "C=US" is not valid under a strict interpretation.
2. 4514 requires spaces to be escaped whereas 2253 doesn't permit spaces 
to be escaped.
Another bug in the RFC 2253 grammar as I mentioned in a prior email [1]
3. 4514 requires null characters to be escaped whereas 2253 doesn't 
permit null characters to be escaped.
This seems like an obscure case.
That's all I found. I think we should add a testcase for each of the 
above cases. If anyone can think of others, let me know.
