SMP specification issue

[Pim van der Eijk <pvde@sonnenglanz.net>]

Hi,

The SMP specification has the following text:

3.5 Referencing the SMP REST binding

For referencing the SMP REST binding, for example from Business Document Metadata Service Location records, the following identifier should be used for the version 1.0 of the SMP REST binding:

http://docs.oasis-open.org/bdxr/ns/SMP/2014/07

This is identical to the target namespace of the SMP schema.

I think this intended to state that this URI value is to be used as the value for the app-service field in the U-NAPTR resource record.    Is that correct?
If that is the intention,  then there is the following problem:

According to RFC 4848, which BDXL references, 

The app-service and app-protocol tags are limited to 32 characters

The above URI has a length of 46 characters.

Kind Regards,

Pim

P.S.   I would also appreciate any feedback on my smp:Certificate question from two weeks ago.
