[Tagging] symbol=* documentation?

I just found this page, which links to country specific mapping of 
hiking paths:


But as I can see, some of these use human-readable explanation of the 
"symbol", so I think my description for the tag was OK and I'll add it 
to the Wiki page if there are no oppositions.  (Using English name in 
"symbol", as Martin recommended.)

 From "osmc:symbol":

"Don't invent a new tag, simply use text/textcolor or refrain from using 
osmc:symbol altogether."

I think we should remove this and allow users to add new values as they 

If this table is "hardcoded" here, everybody will go their own way 
instead using and extending the standard.

All colors should allow all shapes. E.g. currently "blue round" is not 
allowed, but "green round" is allowed as background. This should be up 
to software implementors whether they support specific combinations, but 
not limit MAPPERS from entering real-world information.


Sander, your Belgian tagging could use "color" and "symbol" in one tag, 
that makes it easier for software to read and mappers to write. For 
computer-processed value you could still use osmc:symbol.
