@scope attribute identifies the closeness of the relationship between
the current document and the target resource.
@scopeto "local" when the resource is part of the current set of content.
@scopeto "peer" when the resource is part of the current set of content but might not accessible at build time, or for maps to be treated as root maps for the purpose of creating map-to-map key references (peer maps). An implementation might open such resources in the same browser window to distinguish them from those with
@scopeset to "external".
@scopeto "external" when the resource is not part of the current information set and should open in a new browser window.

If no value is
specified, but the attribute is specified on an ancestor
within a map or within the related-links section, the value
will cascade from the closest ancestor. The
processing default is determined by the value of the
attribute. In most cases, the processing default is "local". However the processing
default is "external" whenever the absolute URI in the
attribute begins with one of the following schemes:
Processors can consider additional URI schemes as "external" by default. Processors MUST always consider relative URIs as "local" by default.
