M:n relations – yaml has missing fields “local” and “foreign”

[GoogleCodeExporter]

Hello. For “many-to-many relations” I use link table with non-standard 
field names. An example of such a model in the attached file. When I get the 
next generation of yaml:
refs_metro
  …
  relations:
    Okrugs:
       class: refs_moscow_okrug
       refClass: refs_metro_okrug_link
       foreignAlias: Metros
       local: id_metro
       foreign: id_okrug
And must be generated:
refs_metro
  …
  relations:
    Okrugs:
       class: refs_moscow_okrug
       refClass: refs_metro_okrug_link
       foreignAlias: Metros
       local: id_metro
       foreign: id_okrug
To solve this problem, I introduced a new tag in the comment, which lists the 
names of the fields for relation. 
{doctrine:mnRelationsSelf}
Okrugs=>refs_metro_okrug_link=>id_okrug=>id_metro=>refs_moscow_okrugs=>Metros
{/doctrine:mnRelationsSelf}
For processing added the following code (version 0.4.2dev, after string number 
855):
-- add m:n relations with self names
    mnRelationsSelf = getCommentToken(tbl.comment, "mnRelationsSelf")
    if ( mnRelationsSelf ~= nil ) then
        for localAlias, refClass, id_foreign, id_local, foreignClass, foreignAlias in string.gmatch(mnRelationsSelf, "(%a+)=>([%a%d_]+)=>([%a%d_]+)=>([%a%d_]+)=>([%a%d_]+)=>(%a+)") do
            refClass = getTable( tables, refClass )
            foreignClass = getTable( tables, foreignClass )
            relations = relations .. "    " .. localAlias .. ":\n"
            relations = relations .. "       class: " .. buildEntityName( foreignClass ) .. "\n"
            relations = relations .. "       refClass: " .. buildEntityName( refClass ) .. "\n"
            relations = relations .. "       foreignAlias: " .. foreignAlias .. "\n"
                        relations = relations .. "       local: " .. id_local .. "\n"
                        relations = relations .. "       foreign: " .. id_foreign .. "\n"
        end
    end
However, I believe its implementation is wrong - the field names should be 
taken from links. Do, please, to the default field names were taken from the 
connection attributes of link.
If this is difficult, you can include in future versions of my code, so I can 
safely update the plugin?
