The description element provides a NLS-enabled text. The text can be parametrized, by creating Parameter Definitions, which point to the unique name assigned to this Text element The nls-ref element is used to specify localized information, which is defined externally (e.g. in a Java Resource Bundle). The key for lookup of the appropriate information is specified as part of this element. A reference to the place where the NLS Mapping is provided must be specified. nlsRef can be used within any other element that requires an NLS string to be displayed, for instance in the title element. The nls-string element is used to specify localized strings during development. It is expected that users will switch to using resource bundles when the product has been NLS enabled and ready to ship. The xml:lang attribute enables a programmer to get started with the code without having to define a resource bundle right at the start. The value of the xml:lang attribute should adhere to RFC 1766 (http://www.ietf.org/rfc/rfc1766.txt). The default value of the xml:lang attribute is English(en).
