[erlang-questions] GPL3 - EPL compatibility

Hello erlang hackers :

I'm planning to develop a erlang program and i want to release it under gpl3
i read, in the gnu web page, epl (mpl 1.0 based license) is not compatible
with GPL(2/3).
In this page http://www.gnu.org/licenses/license-list.html gnu layers
explain this ...
Mozilla Public License (MPL)
This is a free software license which is not a strong copyleft; unlike the
X11 license, it has some complex restrictions that make it incompatible with
the GNU GPL. That is, a module covered by the GPL and a module covered by
the MPL cannot legally be linked together. We urge you not to use the MPL
for this reason.

However, MPL 1.1 has a provision (section 13) that allows a program (or
parts of it) to offer a choice of another license as well. If part of a
program allows the GNU GPL as an alternate choice, or any other
GPL-compatible license as an alternate choice, that part of the program has
a GPL-compatible license.

So , if EPL don't have the MPL1.1 section 13 , EPL is not GPL compatible.

But, in the other hand, the ejabberd2 license was released under GPL2.

So my questions are  :
* can i release source code under GPL3 or 2 using Erlang?
* if i can't do it , can erlang team to consider add the section 13 to the
EPL license and make it GPL compatible ?
