        <pre>An abbreviation is used as a popular term from software development at various
places.

Examples:
- Internal Design and Implementation
  <a href="http://clang.llvm.org/features.html#design">http://clang.llvm.org/features.html#design</a>

- Cross-referencing ...
  <a href="http://clang.llvm.org/doxygen/group__CINDEX__CURSOR__XREF.html">http://clang.llvm.org/doxygen/group__CINDEX__CURSOR__XREF.html</a>


I would appreciate if this term can be unambiguously described.

A - abstract
S - syntax or semantic
T - tree
    Can it be that the data structure which is actually used here is not a
"tree" any more so that it should be generally be called a "graph"?
