унифицированный идентификатор ресурса (URI), включая URL или URN (uniform resource identifier (URI), including a URL or URN)
Ошибки (баги) (Bugs)
Documentation may be placed in a variety of locations, so there
currently isn't a good URI scheme for general online
documentation in arbitrary formats. References of the form
<file:///usr/doc/ZZZ> don't work because different distributions
and local installation requirements may place the files in
different directories (it may be in /usr/doc, or /usr/local/doc,
or /usr/share, or somewhere else). Also, the directory ZZZ
usually changes when a version changes (though filename globbing
could partially overcome this). Finally, using the file: scheme
doesn't easily support people who dynamically load documentation
from the Internet (instead of loading the files onto a local
filesystem). A future URI scheme may be added (e.g., "userdoc:")
to permit programs to include cross-references to more detailed
documentation without having to know the exact location of that
documentation. Alternatively, a future version of the filesystem
specification may specify file locations sufficiently so that the
file: scheme will be able to locate documentation.
Many programs and file formats don't include a way to incorporate
or implement links using URIs.
Many programs can't handle all of these different URI formats;
there should be a standard mechanism to load an arbitrary URI
that automatically detects the users' environment (e.g., text or
graphics, desktop environment, local user preferences, and
currently executing tools) and invokes the right tool for any
URI.
