The displaying of attribute-lists in an "Attribute Reply" (ATTRRPLY) seems to
be written to display some special non-conforming attributes. Conforming
attributes are either displayed wrong or not displayed at all.
When displaying an attributes-list in a "Service Registration" (SRVREG), the
attribute list is only displayed as a single string (and usually truncated).
While this is not wrong, it should be broken up into the comma separated
attributes as "Attribute Requests" tries to do.
Example: (of wrong display)
Service Location Protocol
