4.4.3.1. getSupportedEditExtensions

The getSupportedEditExtensions method has to return a list of all file extensions (in lower case) for which the content handler shall be available as editor application. In our example, the editing of text files and content nodes (XHTML) shall be supported. Therefore, the getSupportedEditExtensions method has to return the file extensions "txt" and "content":
    public String[] getSupportedEditExtensions()
    {
        return new String[] { "content", "txt" };
    }
Note that the extension "content" has a special meaning: If the getSupportedEditExtensions method includes
the extension "content", then the editor supports editing of nodes with type org.docma.plugin.PubContent (XHTML content-nodes).
