How to create a point feature from two intersecting lines within a polygon?

I am trying to create a point feature class within a polygon feature where the two line features intersect/touch (photo below)

The to and from in each polyline is inconsistent

 

 

 

In some cases, the two lines do not intersect, but will touch if the line is extended (below)

For the non intersecting lines, you can have a look at my Line to Intersection Extender custom transformer from the 2018 fme hackathon. https://knowledge.safe.com/questions/83658/fme-challenge-12-days-of-fme-hackathon-2018.html

Have a look at the Intersecor transformer.

The Node output indicates and intersection of lines.

Next the PointonAreaOverlayer would give you an indication (_overlaps > 1) if the intersection is inside a polygon.

Hope this hepls.
