The content files are converted to 2 kinds of trees:
- A TPasElement tree.
- A link tree.
The link tree is used in TFPDocEngine.ResolveLink and THTMLWriter.ResolveLinkID
The paselement tree is used by the parser to find identifiers (classes mostly,
for inheritance trees), so there are less TPasUnsolvedTypeRef instances.

The purpose is to try and let the parser resolver find identifiers as if they had been parsed.
(compare it to the info in a .ppu file)
