(Use MetadataSchema::Create() to create a new schema.)

Parameters

  mixed | $SchemaId | ID of schema. Schema IDs are numerical, except for two special values SCHEMAID_DEFAULT and SCHEMAID_USER. (OPTIONAL, defaults to SCHEMAID_DEFAULT)

  string | $FileName | Name of XML file.
  bool | $TestRun | If TRUE, any new fields created are removed before the method returns.
