Yes, IMO it is not only acceptable to document newly invented tags but 
also advisable to do so.  Note however inventing tags in this context 
means actively using them, not theoretical inventions along the lines 
of "I would like mappers to tag things this way therefore i document 
the tag as if it was being used".  Elaborate tagging schemes should be 
discussed before being used and not be invented ad hoc by individual 

The reason is - as you mentioned - the "Any tags you like" principle.  
It means you can and should invent new tags for *things no tag exists 
for so far*.  To allow mappers to determine if there is already an 
existing tag for a certain type of feature tags have to be documented.  
Or looking at things the other way round:  If inventing new tags is 
encouraged but it is discouraged to document them in a way that can be 
easily found by other mappers that would massively emphasize tag 
proliferation since mappers will repeatedly invent new and different 
tags for certain things because they are unaware that another mapper 
has already invented a tag for this.
