Suppose I have a template for creating documents, and I want to render a document from the template. It would be grammatically correct to call this action "rendering a document" or "rendering a document from a template," but calling it "rendering a template" or "template rendering" would be grammatically incorrect, because the template isn't the object that's being produced -- it is the source from which the document is being produced.
Is there a verb that represents the action being done to the template when the document is rendered from it?
