A better way to create a hierarchical namespace seems to be to use
some character _other than_ '.' (dot) to separate the levels.

For instance:

  Pxp_document
  Net_httpclient   (nearly)

This allows a third party to come along and add packages to the same
"namespace", eg. Pxp_myextension.

Using dot / -pack doesn't allow extension and doesn't allow the package
to be spread over several cma files.

Rich.

(I'm not claiming that I've used this convention in my own packages,
but I ought to have done ...)
