Hello,
what is the meaning of these changes?
Because:
1) such value can be calculated anytime, it is not needed to store it in the OSM database,
2) the source used is  "SRTM" which is very inaccurate, but there is more accurate source, e.g. "DMR 5.0",
3) the tagging is wrong, as the prefix "ele:" is used for storing values in specific datums, e.g. "ele:wgs84". There is no such datum as "source"... I believe, that you wanted to use the "source namespace", i.e. "source:ele", see the wiki: https://wiki.openstreetmap.org/wiki/Key:source#Multiple_source_tags_.28historic.29

If you would have followed the rules for imports, and discussed this in advance, we could avoid this mess ☹️
