[wg/solid] describe deliverables and their dependencies more precisely

[pchampin]

Beyond the main deliverable ("Solid Protocol v1.0") adopted from the CG,
the charter should describe in more detail how it will deal with the various dependencies of that document:

• which ones are meant to be adopted by the WG as other REC-track documents, and
• how the WG intends to deal with other normative references with an insufficient level of maturity.

From https://lists.w3.org/Archives/Public/public-new-work/2023Oct/0007.html

• The one normative deliverable Solid Protocol (per
  https://www.w3.org/2023/09/proposed-solid-wg-charter.html#normative) has
  dependencies
  (https://www.w3.org/2023/09/proposed-solid-wg-charter.html#dependencies) on
  specs that are all currently only in a CG and are thus unlikely to make it
  to CR or REC any time soon thus blocking progress beyond Working Draft
  (WD). It is my understanding that normative references in W3C REC-track
  documents MUST only refer to (normatively depend on) specifications at or
  at most one maturity level below. E.g. a WD can depend on EDs, but a
  Candidate Recommendation (CR) can only depend on WDs and above. Without a
  concrete plan for reducing dependencies or advancing those dependencies
  along a standards track, this appears to be a blocking issue for the one
  normative deliverable.
• The Dependencies section
  (https://www.w3.org/2023/09/proposed-solid-wg-charter.html#dependencies) is
  misleading. That section says "Depending on the Working Group progress,
  including consideration for adequate implementation experience, the Group
  will also produce W3C Recommendations for the following documents". It is
  misleading to only put these documents in a Dependencies section. The prose
  "the Group will also produce W3C Recommendations" seems to imply these are
  actually all additional normative deliverables within scope of the Charter,
  yet they are explicitly listed outside of the Normative Specifications
  section.

This clarification also concerns the reference to Solid QA in the success criteria.
