Returns a row per XML schema collection. An XML schema collection is a named set of XSD definitions. The XML schema collection itself is contained in a relational schema, and it is identified by a schema-scoped Transact-SQL name. The following tuples are unique: xml_collection_id, and schema_id and name.
| Column name | Data type | Description |
|---|---|---|
| xml_collection_id | int | ID of the XML schema collection. Unique within the database. |
| schema_id | int | ID of the relational schema that contains this XML schema collection. |
| principal_id | int | ID of the individual owner if different from the schema owner. By default, schema-contained objects are owned by the schema owner. However, an alternate owner may be specified by using the ALTER AUTHORIZATION statement to change ownership. NULL = No alternate individual owner. |
| name | sysname | Name of the XML schema collection. |
| create_date | datetime | Date the XML schema collection was created. |
| modify_date | datetime | Date the XML schema collection was last altered. |
