The first hanging paragraph under 4 Platform Deployment Package reads:

*****
The Platform Deployment Package (PDP) ensures portability across platforms. It can be created by a platform to export to another platform, which then imports it. It can also be created by an Application Development Environment running locally or deployed as Software as a Service in the cloud. The PDP (and the Plan file, see Section 4.2, “Plan Overview”) defines the formats for on-boarding new applications onto a CAMP-enabled Provider.
*****

The purpose of this paragraph isn't clear. Do you mean to say that a PDP archive can be created by means not defined by this specification? I'm not sure of the difference between import and "on-boarding new applications onto a CAMP-enabled Provider." I assume existing applications can be imported as well. Yes?

Suggestion: The paragraph specifies no normative content nor does it advance the defining of a PDP. Just delete it.
