It seems that all syntax diagrams have the same issue:

That what should be declared is repeated in the declaration
itself which makes no sense to me.
A syntax diagram for 'type declaration' (which is written in the heading already)
cannot have the text 'type declaration' again in the diagram.
The diagram just should explain 'type declaration'.
Following the line should reveal a syntactical correct 'type declaration'
so it should not contain itself the text 'type declaration'.
Otherwise it recursively explains itself in an endless loop.

But that's not part of the Free Pascal documentation.
So it's not available in the documentation of Free Pascal?
Who can know when he has to look at the Delphi
documentation (which version?) and when this differs from Free Pascal?
