1. A computer-implemented method of performing a predefined operation on a data component for a specific context, the method comprising: receiving a user input specifying at least one context value, the user input being made for performing a predefined operation on a data component for a specific context characterized by the at least one context value, the data component being a context specific representation of a context independent data type; reading data elements of the context independent data type in response to the user input, each of the data elements being (1) configured for defining semantics of data in a document that is electronically transmitted between entities and (2)_associated with a harmonization indicator that, when set, causes the associated data element to be included in performing the predefined operation unless the context independent data type explicitly excludes the associated data element for the specific context, and that, when not set, causes the associated data element not to be included in performing the predefined operation unless the context independent data type explicitly includes the associated data element for the specific context; and performing the predefined operation on the data component based at least in part on a setting of the harmonization indicator of each of the data elements.
