+Blender manual:
+The new option Keep Bind Info checks each bone for having two arrays:
+ rest_mat – an array of 16 floats which represent the bone’s original rest-pose matrix.
+ bind_mat – an array of 16 floats which represent the bone’s original bind-pose matrix.
+ Those two arrays can later be used when you want to export the rig again and be sure the original rest pose/bind pose combination must be used.

+(Gaia Clary)
+Back in 2.70 this issue was solved in a very ugly way:
+
+we added a custom transformation to each bone which contains a scale, a rotation and a translation:
+
+restpose_scale_x (default = 1.0)
+restpose_scale_y (default = 1.0)
+restpose_scale_z (default = 1.0)
+
+restpose_rot_x (default = 0.0)
+restpose_rot_y (default = 0.0)
+restpose_rot_z (default = 0.0)
+
+restpose_loc_x (default = 0.0)
+restpose_loc_y (default = 0.0)
+restpose_loc_z (default = 0.0)
+...
+So i proceed as follows now:
+
+ I add the code for creating the custom properties to the Collada importer
+ I add an option to the importer to "import bind pose info"
+ I also add a new option to the exporter "use custom bind pose"
