# xsl:import-schema

Saxon implements the `xsl:import-schema` declaration in the schema-aware product Saxon-SA only.

The `namespace` attribute specifies the target namespace of the schema to be imported. Specify `namespace=""` to import a schema with no target namespace.

The `schema-location` attribute specifies where the schema document can be found. This URI is passed through the URIResolver in the same way as the URIs used on `xsl:include` and `xsl:import`. The attribute can be omitted only if a schema for the required namespace has already been loaded in the `Configuration`, for example if it has already been imported from another stylesheet module.

For further information see Schema Processing.
