| | 3 | This page concerns a proposal to extend the [source:/metadata/trunk/toolkit/general-component-schema.xsd general component schema] with a number of [http://www.schematron.com/ Schematron] rules to specify certain restrictions that cannot be expressed using plain XSD. |
| | 4 | |
| | 5 | Currently a version of this extended schema can be found as a part of the testing resources of the CMDValidate library of the [[ComponentRegistryAndEditor|ComponentRegistry]]: |
