Parameter syntax:

[ implicit_selection ]? |
'uncomment' [ '[implicitNode]' ]?

Without the uncomment option, replace text or node selection by a comment containing this selection.

With the uncomment option, it's the inverse operation: parse the content of selected comment and replaces this comment by parsed XML nodes.

Examples:

commentOut
commentOut [implicitElement]
commentOut uncomment
commentOut uncomment[implicitNode]
