Note FRACTION_COEFFICIENT_2 in specification.

Note FRICTION_COEFFICIENT-2 in X3DUOM and XML Schema.

The schema should be corrected to use _, not -.

Thanks!

Contact : X3DNode {
MFString [in,out] appliedParameters "BOUNCE" ["BOUNCE","USER_FRICTION","FRICTION_COEFFICIENT_2","ERROR_REDUCTION",
"CONSTANT_FORCE","SPEED_1","SPEED_2","SLIP_1","SLIP_2"]

For enum compatibility with schema, X3DUOM, etc.

Underscore versus -

Thanks for careful error reporting. This problem has been corrected and fixes are committed to version control. I expect to be able to update the copies on web3d.org in a few days.
