I was not suggesting any abbreviations. I was trying to confer:
"If a node has an access=public then we should render a P symbol"
"If the nodes has access=private then we do not draw a P symbol"
"If a node has access=permissive then what do we do?"
"if a node has no access= tag then what do we do?"
etc
...

access=public/private/permissive are all listed on Map_Features, it
isn't clear whether permissive should imply a P symbol or not. The
code needs to handle the other cases too.
