On some occasions you may not want a standard schema to be downloaded from the Liquid web site to provide validation and intellisense information for your XML Document.
In order to stop this happening:
1. Run the application.
2. Create a new XMl Document (File->New File...->XML Document)
3. Select Tools->Schema Used to Validate XML. A dialog showing the schemas in the library should appear.
4. Find the schema you don't want to use from the library and click 'Remove Standard'.
