olink — A link that addresses its target indirectly
olink ::= (text | | | | | | | | | | | | | | | | )*
link, the semantics of
olink are application specific. The
olink element provides a mechanism for establishing
links across documents, where ID/IDREF linking is not possible and
URI-based linking may be inappropriate.
In general terms, the strategy employed by
olink is to point to the target document by URI, and
point into that document in some application-specific way.
Other elements can also behave like
using the common linking attributes
xlink:role. When an element has an
attribute, then its
attribute is interpreted using
olink semantics. That
is, the part of
the fragment identifier (#) is interpreted as equivalent to an
attribute value instead of a URI, and the part after the fragment
identifier as an
targetptr attribute value.
olink points to its target primarily with
targetdoc attribute. ...
