1. A system for dynamic XML schema Definition (XSD) enumeration, comprising: a processor; a memory embedded with instructions executed by the processor, the embedded instruction comprising: a receiver for receiving a request from a validation module for XSD file data, the XSD file data for validating XML data; a cache determination subsystem for determining whether the requested XSD file data is contained in a cache; a transmitter for providing the requested XSD file data from the cache to the validation module if the requested XSD file data is contained in the cache; a database query system for using a defined database query to retrieve dynamically from a database data values stored in one or more columns of a database table if the requested XSD file data is not contained in the cache, wherein the data values stored in the one or more columns of the database table are retrieved dynamically from the database table using the defined database query are valid data values for XML data; an XML structure generator for generating XML structures in response to the retrieved data values, wherein the XML structures enumerate the valid data values for XML data; an XSD generator for generating XSD file data comprising the generated XML structures, wherein the XSD file data comprising the enumerated valid data values for XML data; a caching subsystem for caching the generated XSD file data; and wherein the transmitter provides the cached XSD file data to the validation module.
