Discovery 5.1.3 - I can't quite parse it

[Martin P Pain <martinpain@uk.ibm.com>]

Discovery:

5.1.3 Servers SHOULD only use of LDPRs
representations for discovery details unless there are scenarios where
it would be valuable to have that data readily available for purposes such
as query. 

should this be the following?

5.1.3 Servers SHOULD only use methods
defined by LDPR (for example, the Link header in 5.2.2) for discovery details
unless there are scenarios where it would be valuable to have that data
readily available for purposes such as query. 

or does it mean

5.1.3 Servers SHOULD only use Link headers
for discovery details unless there are scenarios where it would be valuable
to have that data readily available for purposes such as query.
