1. A method for extensibility of binding definitions for a user interface application, the method comprising: performing, by a computer system programmed with code stored in a memory and executing by a processor of the computer system to configure the computer system into a machine: obtaining a framework having definitions of a first set of rules for a first grammar level used for interpretation of binding specifications to a user interface application, wherein the user interface application is incompatible with the first grammar level; performing a first transformation of the framework to generate the first set of rules for interpretation of the binding specifications in the first grammar level; performing a second transformation of the framework to generate a first presentation style for the first grammar level; obtaining the binding specifications in the first grammar level, the binding specification conforming to the first set of rules; and applying the first set of rules and the first presentation style to the binding specification to generate output binding specifications in a second grammar level compatible with the user interface application.

The method of claim 1 , wherein the obtaining a framework comprises: obtaining at least one file having contents comprising grammar definitions conforming to a second set of rules; and transforming the contents of the at least one file into the framework using a second presentation style conforming to the framework.
