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 the settings you select the assignment of the document types (Document Type Association). Then click on "New" to create a new association
In the first tab you have to click on the '+' to create an assignment.
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.
