[Tagging] pressurized=* on pipelines

[François Lacombe]

Hi all

Indeed pressure=no mostly refers to vacuum, instead of normal atmospheric
conditions.

Shouldn't we consider following values as to prevent the need of two tags
to state if it's pressurised and which normal pressure?
* pressure=yes : Unknown pressure > 1 atm (1.013 bar)
* pressure=atmosphere : Normal atmospheric pressure at the feature
elevation (default).
* pressure=no : Primary vacuum (< 100 Pa). Useful for kind of hyperloop
tunnels for instance.
* pressure=]0;+inf[ : Fixed pressure.

Units will undoubtedly be an issue as Pascal is the international system
unit but many fields of knowledge still prefer many others (bar, psi,
atm...).

I see no issue with this and feel free to correct/complete

All the best

François
