I'm not questioning reality, I'm questioning design.

The 'mount' semantic where designed to mount 'sub-sitemaps' not
'sup-pipelines'.
This because we thought that 'sitemaps' should be modularized, not
pipelines.
Whether this is a good design choice or not, it's up to discussion. No
problem with that.

Reading both Berin's and your comment, I started thinking that some of
my original design ideas might be too limiting and not really necessary.
See my next email on the subject.
