Woe, nice work Pieter! You are going for it.

• Would it be possible that it spits out all the errors at once instead of one by one?
• Could it give a warning if nothing is found in the last column (the link)? Currently it gives an error if you don't add the last ; but it accepts an empty spot
• Also, the first line does not have to follow the [path] ; [category] ; [remark] ; [link] format because it can state something generic like: new profile not present in 2020 release or somekind.

For example, I have the following for AnatomicalLocation that throws an error for zib-AnatomicalLocation-BodyStructure profile:

## AnatomicalLocation 
### zib-AnatomicalLocation
* `CodeableConcept` ; textual ; Refined guidance for Location and Laterality ; ZIBFHIR-113
* `.extension:bodyStructureReference` ; extension ; Replaced ExtAnatomicalLocationLaterality with BodyStructureReference for Laterality ; ZIBFHIR-113
* `.extension:bodyStructureReference` ; mapping ; Moved mapping of Laterality to `BodyStructure.locationQualifier` ; ZIBFHIR-113

### zib-AnatomicalLocation-BodyStructure
* New profile that maps Laterality to a native FHIR element inside the BodyStructure resource instead of a custom extension (ZIBFHIR-113).

Possible yes, but a bit too much work (for now)

* Could it give a warning if nothing is found in the last column (the link)? Currently it gives an error if you don't add the last ;  but it accepts an empty spot

It throws an error now, and also throws an error if the issue keys are not formatted correctly.

* Also, the first line does not have to follow the [path] ; [category] ; [remark] ; [link] format because it can state something generic like: new profile not present in 2020 release or somekind.

Fixed this and added the option to have issue keys here as well. It doesn't check if this is the first line though.

Nice improvements Pieter. Let's go!
