I noticed the repeated "the the" in the the query elevation documentation.
If either one of these parameters is specified at request time, the the[sic] entire elevation configuration for the query is ignored.
I have prepared a PR with all similar occurrences in comments and documentation replaced, but not blindly. Seems like a particular choice was probably made for some of the tests, and maybe that bled into the docs? Maybe an inside joke?
In any case, let me know if you want the PR submitted.
