should there be a TypeStd table?

It turns out there are actually types which have documentation. This
is probably okay, types are documented in LSB by appearing in Data
Definitions sections.

Just wanted to raise the question. For example, the Gnome project has
documentation links for FunctionPointer types, such as in this example:

https://developer.gnome.org/gtk3/3.6/gtk3-Keyboard-Accelerators.html#GtkAccelGroupActivate

A TypeStd mapping table would allow LSB Navigator to point to the
upstream page for these types. In the example pasted here, there is
no content to the type doc except the "prototype" (function pointer
definition), I'm not sure whether that's true for the other types or not.
