Hi Mark,

Generally like this... a little gnit with the wording...

'these' is a little indirect. The most recent 'these's' seems to be HTTP.

Suggest something like:

	"As a result, binding definitions for underlying protocols with
well-known default ports or application profiles SHOULD document potential
(harmful?) interactions with commonly deployed infrastructure at those
default ports or in-conformance with default application profiles. Binding
definitions SHOULD also illustrate..."
