Where in the documentation would one find that interface documented in order
to review that aspect?

I think this ommision is what's leading to the perception that the library
is an xml library, or a command line library, or a... That along with the
fact that nearly 1/2 of the documentation deals with describing these
specific parsers.

My vote on the current property_tree submission is NO. I think it could be
re-submitted in the future given a clear rationale accurately stating:

- it's intended use
- a comparison with similar libraries (have you looked at McObject's
ExtremeDb as one example)
- why/why not it's not based on boost.graph libray as a
- why/why not it interacts with trees in spirit
  [Joel recently mentioned a fusion tree on the spirit mailing list]
- why would I not just use map< vector<string>, data > along with
upper/lower bound
  [or a TST based map]

Without these the criteria required for review is a floating target.

Other specific issues needing to be addressed include:

- clear separation of the library from specific instances of it's
  [ala boost.iostream filters for zlib...]
- string/separator/paths (see other postings in this thread)
- possible merging/interaction with proram_options library
