Hello, I've found that we use in our XML dump: <uuid>%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x</uuid> it's strange format of the UUID string representation. Is there any reason for this format? I think normal (rfc4122) is format: "%02x%02x%02x%02x-%02x%02x-%02x%02x-%02x%02x-%02x%02x%02x%02x%02x%02x" it means with '-'. Karel -- Karel Zak <kzak@xxxxxxxxxx>
