Open an existing XML Schema file in the XML Schema editor
to view or edit the contents of the file.
To open an existing XML Schema file:
Right-click the XML Schema file (file extension *.xsd)
that you want to open, and select Open. The XML Schema file opens in the XML Schema editor.
Tip: The Eclipse framework lets you open resource
files with other editors. However, you are advised to use the XML
Schema editor to work with XML Schema files. This editor correctly
validates any changes that are made to your XML Schema files. Other
editors might not correctly validate files.
