Browser	Version	Result	Notes
BS Contact	7.107	Not Expected	Follows the X3D-Spec: read on foo gives you the field value, but foo() as function gets also called. Breaks the ECMAScript spec.
FreeWRL		Not Expected	No support for inputOutput
Octaga	2.2.0.12	Not Expected	same as bscontact but addition initialize() is not called. Breaks the ECMAScript spec
Instant Reality	2.0.0_beta4	Not Expected	reading foo returns the function not the field value. foo() funciton gets called. Does not break X3D or ECMA spec but field value is not accessible.
Vivaty	2.1	Expected
Xj3D	2_M1_DEV_2008-06_02	Expected
