Dear interested users, the next version of Encode-Arabic will probably include these features:
1) Encode::Arabic::ArabTeX might treat <T> as <t> if the former is supposed to appear in its initial or medial form. Thus, morphological inflection will become simpler. In effect, <madrasatAni> and <madrasaTAni>, for instance, would produce one equivalent representation.
2) The options enforced by enmode and demode might become lexically scoped with respect to the package they appear in.
Let me open a discussion on this direction of the development ;)
