Documentation can be extracted with doc node :

https://glayzzle.com/docs/CommentBlock.html

In order to enable documentation extration (disabled by default), you have to set extractDoc to true on the parser component.

The documentation node will only contain an array of lines, but will not enter into parsing annotations. In order to do this, you have to use this complementary project :
