questions to differences between RFC2253 & RFC4514

[Peter Marschall <peter@adpm.de>]

Hi,

I am currently in the process of updating the DN parsing routines of perl-ldap 
and found some differences on border cases between RFC 2253 & RFC 4514

As you are more knowledgeable than I in LDAP (you wrote the specs ;-),
could you please give me your opinion on the test cases below and whether my
interpretations are correct.

Thanks in advance for your help
Peter
