Abstract: A document management system generates a document template within which a user can embed document tags. Each document tag represents a term of the document. The user selects a document tag and identifies a location for the document tag within the document template. The embedded document tag adheres to formatting rules of the document template. The document management system accesses a data value corresponding to the selected document tag and generates a modified document. The modified document includes the accessed data value at the identified location, and is subject to the formatting rules of the document template.
