<br><br>The opportunity to access the source geodata in OSM enables multiple datasets to be merged before rendering. Whether the data comes from OSM or somewhere else is unimportant - the ability to merge it before rendering *is* important. A very easy way to achieve that is to store both datasets in OSM, using tag prefixes, if neccessary, to keep them separate and managable.
