Section 4.5 of the json1 documentation begins its third paragraph with:
Edits occurs sequentially…
The second word should be "occur". This typo also occurs in the second paragraph of Section 4.8.
The third paragraph of Section 4.6 also contains a typo:
An argument with SQL type TEXT it is normally…
The word "it" does not belong.
The first paragraph of Section 4.8 reads in part:
… returns a new JSON value that is the X with all the elements…
"the X" should probably be "the input X".
