an abstract description of one of the interfaces defined
by this service standard.
This element can provide details about the interface
that apply to all implementations. Each interface
element should specify a role with a value starting
with 'std:' or, if there is only one standard interface,
is equal to 'std'.
Applications that, for example, wish to build a GUI
to the service on-the-fly would first access this generic
description. Site-specific variations, such
as supported optional arguments or site specific
arguments, would be given in the actual implemented
service description and overrides any common information
found in this generic description. This generic interface
description can be matched with the site-specific one
using the role attribute.
Even though the Interface type requires an
accessURL child element, this element is
intended to describe a service in the
abstract--i.e. without reference to a particular
installation of the service. Consequently,
the accessURL may contain a bogus URL;
applications should not expect it to be resolvable.
the version of the standard that is recommended for use.
More than one version can be listed, indicating
that any of these versions are recognized as
acceptable for use.
when present, this element indicates that all
versions of the standard are considered
deprecated by the publisher. The value is a
human-readable explanation for the designation.
The explanation should indicate if another
standard should be preferred.

Note that when this resource is a Service, this
grade applies to the core set of metadata.
Capability and interface metadata, as well as the
compliance of the service with the interface
standard, is rated by validationLevel tag in the
capability element (see the VOResource:Service complex
type).
