OVERVIEW: FEATURE SUMMARY: Add API to access compile-time context of current compiled element from programs and annotation processors. MAJOR ADVANTAGE: Now compile time properties are unaccessible for programmer. This meaning

No, this flavor information has been officially accessible for programmers using Java SE 6 compilers, which are required to support annotation processing and the JSR 199 tools API. See the javax.annotation.processing and javax.tools packages, which use javax.lang.model.

The view of a type provided by JSR 269 annotation processing is read-only, but much of the effect of modifying the file can be had by either generating subclasses or the superclass of the type in question.

These APIs don't provide a direct notion of location, but the Messager accepts the model of a program element to emit location information.
