List all factors that will be evaluated in the import.

- Convert them as .osm file. (done)
- Run JOSM validation on each .osm file.
- Load .osm file to JOSM, and download raw data for target area.
- Conflate with existing data.
- Changeset size policy
None, the most biggest file size is 704kb (7484 objects).

So if some problems happen, I'll revert it's changeset one by one.
Existing data has priority.
Will be checked by JOSM validation.
