[mkgmap-dev] tag values of relations and tag values of its members

Hallo, is there any way to use the tag values of the members of a relation within the apply command in the relations style file? With apply {set Member_Tag_Value=${Relation_Tag_Value}} I can set the tag value of the relation to all its members. Instead of just setting the tag in the member, I would like to combine it with a tag value from the member. Something like apply {set Member_Tag_Value='${Member_Tag_Value} and ${Relation_Tag_Value}'} Can this be done somehow? And as a related question: I it possible to include tags of the member of the relation in the tag test of a relation rule? Gruss Torsten
