Empty vcard show as valid

[xbgmsharp]

Empty vcard are count as valid even so there is no value.
Here are 2 samples:

BEGIN:VCARD
UID:4165-4FBBCC00-33-9470200.vcf
VERSION:3.0
CLASS:PUBLIC
PROFILE:VCARD
END:VCARD

Or

BEGIN:VCARD
VERSION:3.0
PRODID:-//Apple Inc.//Address Book 6.1.2//EN
UID:bb332361-6c7e-4782-babd-d7d5a5f158f4
END:VCARD

The count check should return something different than the NB card as there is no value.

I have been thinking about it, and i could find any other way than compare the entry and ensure they are not the only onee present. It does looks like a good idea as it there is 2 parsing.
What do you think would be a good approach to avoid non valid (empty) vcard.
