XML Schemas enable document designers to specify the allowed structure and content of an XML document and to check if an XML document is valid.
Oxygen provides a simple and expressive Design page for editing XML Schemas. The schema diagram helps both the content authors who want to understand a schema and schema designers who develop complex schemas.
The diagram font can be increased using the usual Oxygen shortcuts: (Ctrl - +) , (Ctrl - -) , (Ctrl - 0) or (Ctrl - mouse wheel). The whole diagram can also be zoomed with one of the predefined factors available in the Schema preferences panel. The same zoom factor is applied for the print and save actions.
