Hi,

if I set a tag to '' in the style file is it then treated as unset ?

example:

{set motorcar = ''} (or should it be ""?)

and later in the style file:

{add motorcar = yes}

now what is the value of motorcar: unset, blank or yes ?

it's blank, but set, so 'add' will be ignored. Used 'delete' as action.
