A computer implemented method, system, and/or computer program product modifies a master template for an executable document. A version architecture comprises a master template for a master document, a new variation document that describes what changes are to be made to the master template for a specific context, and a resulting modified template based on the master template and rule-based instructions found in the new variation document. A processor defines an executable master document from the master template that, when executed, produces a final product. Specific rules set out conditions for modifying the master template for the specific context. These specific rules are used to define a new variation document, which is applied against the master template to generate a context-specific modified template. The context-specific modified template is then used to generate a context-specific executable document that, when executed, generates a final context-specific product.
