fixes #168, but for some reason the issue does not appear in the Development automation. So I leave it referenced here.

Agree with the Pascal/Watt/Decibel changes, hesitant about SWL/SPL.

@berlotti, @CBenghi, do you agree to add this fix also to the documentation of IDS1.0, not just IDS1.1?

Can't we just use 'decibel' unit, without the SPL/SWL? Whether it's the perceived noise (SPL) or source specs (SWL) it's defined in a property.

I was attempting to ensure that the identification was unique.
But it can be resolved by the measure in context.

simplified db units.
