Is 'null' ever valid syntax?
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
I suppose this is either always true or false, right?
if ( attributeType.getSyntax().getSyntaxChecker().isValidSyntax( null ) )

I think ( to be double checked) that we allow a Value to old either ""
or null.

I have no idea about the checkers, but an empty string isn't a null string.

No. For example the directory string syntax doesn't allow an empty
string, so in that case the syntax checker returns false. But the IA5
string syntax allows an empty string, in that case the syntax checker
returns false.
Kind Regards,

No. It depends on the AttributeType. Some accept null values, some
don't. This is the reason we have such a test.
