Translation map.

Used to translate every COLLADA id to a valid id, no matter what "wrong" letters may be

|
included. Look at the IDREF XSD declaration for more.
|
|
Follows strictly the COLLADA XSD declaration which explicitly allows non-english chars,
|
|
like special chars (e.g. micro sign), umlauts and so on.
|
|
The COLLADA spec also allows additional chars for member access ('.'), these
|
|
must obviously be removed too, otherwise they would be heavily misinterpreted.
