Version 1654 was commited by elrond on 2010-06-28 22:40:57 +0100 (Mon, 28 Jun 2010) RuleSet: Update usedTags after merging other RuleSet Issue: If you have a style A that has a base style B, only the main tags from A are considered. This means, that many rules from B are not used. I haven't tracked down exactly why and where it happens, but I assume, that some code cleans up the osm data straight after/while reading it and removes any "useless" tags. To save memory. Anyway, I found a solution: Update the "usedTags" of the RuleSet after merging in the base-RuleSet.
