This is about the XML element generic/comments - singleLine and multiLine comments.
Including
- comment type
- startLine
- position [column 0, or before first non-space]
- endLine: [only for multiline comments]
- region: [folding ID, only for multiline comments]
- nesting: *thinking aloud* maybe even a bool whether nesting of multiline comment is supported ?
Think about this more + API how to expose this.
