One of the issues created by the incomplete glossary is the use of "archive" in 4.1, 4.1.1 and following.
4.1 PDP Package Structure reads:
*****
A PDP is an archive which contains a Plan file named camp.yaml at the root of the archive. A PDP archive MAY include other files related to the application including, but not limited to, language-specific bundles, resource files, application content files such as web archives, database schemas, scripts, source code, localization bundles, and icons; and metadata files such as manifests, checksums, signatures, and certificates. [PDP-01]
*****
The phrase, "... at the root of the archive" implies that an "archive" may have nested directory structures. That is the essence of having a "root." However, the following enumeration fails to mention any such directory structures.
Moreover, 4.1.1 Supported Archive Formats reads:
*****
A Provider SHALL support the following archive formats for a PDP:
A PDP as a ZIP archive [ZIP] [PDP-02]
A PDP as a TAR archive [TAR] [PDP-03]
A PDP as a GZIP [RFC1952] compressed TAR archive [PDP-04]
Providers MAY support additional archive formats for the PDP. [PDP-05]
*****
Also wrong because ZIP, TAR and GZIP are compression formats, not archive formats.
