Documentation comments

[lars-reimann]

Is your feature request related to a problem?

Handling of documentation comments needs to be improved:

• If the declaration has annotations, the documentation is not associated properly to it.
• @param is not linked to the appropriate parameter (same for a possible @result/@typeParam...). This information should be shown in the hover provider, for example.
• No syntax highlighting of special elements inside (e.g. @param).
• No validation of documentation comments (e.g. info/warning if some but not all parameters are documented).
• * is not added at the start of lines after pressing enter.
• * is not removed if lines are joined.
• Change tag rendering for typeParam, param, and result.
• Document format
