Correct, bacause the basedir has no meaning as the file is imported.
What about ant.projectdir and ant.projectdir.projectname properties?

IMHO the latter.

Explaining a bit more my cases:

  1) I have a project that is made only to be imported:
     <fragment name="">...</fragment>

     - Ant will deny the use of it standalone -

     I would need this when I use the ant.file.currentproject
     property that is not available when I run it standalone.
     (although we could as well put it, and so this use-case
     looses meaning it seems)

  2) I have a project that is not made to be imported:
     <project importable="false">...</project>

     - Ant will deny the use of it as imported -

     This project does not check that the resources and paths
     are resolved using the ant.file.projectname property, and
     thus would not work properly if imported.
     In this case the name attribute is mandatory.

  3) I have a project that can be imported or used as-is:
     <project importable="true">...</project>

     - Ant will never deny it's use -

     This project does not use external resources, or
     checks for them in a manner that works in both scenarios.

  4) I have a project that does not say if it can be imported:
     <project importable="true">...</project>

     - Ant will never deny it's use but warn if it's imported -

     The author does not tell you how it's meant to use.
     Most probably it's not made to be imported, so if you want
     to import it, good luck!
