General usage instructions

The plugin automatically recognizes RELAX-NG files in XML syntax by their namespace URI and treats *.rnc files as compact syntax files (the extensions can be configured via Settings|File Types).

To make use of a RELAX-NG schema for editing XML documents, associate the XML namespace-URI with a RELAX-NG file via Settings|External Resources.
