OxygenXML

The editor oXygen XML is a special XML editor that provides excellent support for editing the layout rules. To get this support, the schema must be assigned to the speedata layout namespace (urn:speedata.de:2009/publisher/en).

In this window you enter the namespace of the layout (urn:speedata.de:2009/publisher/en).

Now you can set RELAX NG + Schematron and select the scheme. In the ZIP file it is located under share/schema/layoutschema-en.rng or …​-de.rng, depending on the desired language for the short description.

From now on, for every layout in the namespace

xmlns="urn:speedata.de:2009/publisher/en"

the schema should be associated with the layout. This can be checked by the fact that a selection of commands now appears when you enter an opening angle bracket (<).

If the scheme is correctly integrated, a selection list appears as soon as a command is entered.
