Do you have to know how to write a kosher get or believe the correct things for a get you've written to be kosher?

I ask, because here it is said that "The late Conservative Rabbi Boaz Cohen comes to mind. His gittin were accepted by the Rav and the RCA."

and here R. Boaz Cohen wrote

"I am convinced that only through creative interpretation shall we be able to solve our present-day problems in the spirit of the great exponents of historical Judaism, such as Frankel, Graetz and Schechter."
