Hi Henning,

the list need not contain all tags of the style file because the ways 
are merged after the style files are processed and before the 
intermediate garmin objects are created.

One simple example:
Way 1: highway=motorway,ref=A 1
Way 2: highway=motorway,bridge=yes,ref=A 1
Way 3: highway=motorway,ref=A 1

The three ways are connected (1-2-3).
The style file creates for each way a 0x01 garmin motorway and an 
overlay for the bridge. The 0x01 ways can be merged without considering 
the tag bridge=yes.

Only those tags evaluated by mkgmap internally after the style file 
processing need to be considered.
