With the editArticle command there are several parameters. I understand sBody, sHeadline, ixPersonEditedBy and of course ixWikiPage.
I am guessing that dt is the editing date, which is weird since i think the server should set that.
I understand sTags is a comma-separated list of tags. Is it case-sensitive?
Is sComment the edit comment? And what is the cols parameter used for?
Perhaps it would be easier to understand if there was a sample Payload for that on the API page.
Oh and are all parameters required?
