[mkgmap-dev] NumberFormatException when making marine chart

Thanks for the hint.
The first one I found is seamark:light:character.
I think a bit more complicated are sectors of lights since the sector 
number is part of the tag. They are tagged with seamark:light:# or more 
detailed with seamark:light:#:<attribute>, where # is the sector number 
and <attribute> describe the sector. This will result in a large number 
of extra used tags (I found a light with 9 sectors, each having 4 
required tags). So it would be nice if we could use placeholders:
	extra-used-tags=seamark:light:*

Todays implementation handles only the first, compact form with only one 
tag per sector. I will try to work out a patch to support both.
