Why are publicly available schemas provided?
We provide access to existing XML schemas, such as UBL and the Grants.gov schemas, so that users may validate instance data against those schemas or extend those schemas without downloading and installing the schemas for themselves. We hope to expand the number of schemas that we make available in this way as well. Our experience with an earlier project showed this to be extremely useful in analyzing the impact to data as schemas changed. For example, we could have the latest and greatest version of a schema installed on our website and a user could test their data with the new version before migrating to the new version of the schema in their own environment.
