redirected it to that list.]

You can pass properties down, but not up.

If you don't intend to ever run the sub-project buildfiles themselves,
then just always have the "root" buildfile run them (name your sub-project
buildfiles something other than build.xml, if you want to execute 'ant'
from a subdir but still have it run against the "root" buildfile [see the
"-find" option).

If you do intend to let your sub-project buildfiles be run independently,
then you can either go with the "entity include" described in the FAQ at:
  http://jakarta.apache.org/ant/faq.html#xml-entity-include
or, if you're worried about getting lost in a maze of relative paths, you
could put your global properties in a property file, and have each
buildfile read that file in, using:
  <property file="<global_properties_filename>"/>
