Hmm, that text could do with a bit of technical clean-up. May I
suggest some revised wording? How about something like the following?

===
The longdesc attribute may be present and contains a valid non-empty
URL potentially surrounded by spaces referencing a Web resource that
contains detailed information about the image that the Web page author
wants to make available, but not in the main flow of the Web page. The
longdesc resource will in particular contain a textual description of
the content of the image that accessibility technology will make
available to vision-impaired users.

The user agent should expose the longdesc link to the user, but it
should not interfere with the page's normal rendering. For example, it
could be exposed in the image element's context menu.

Note: The longdesc page can be regarded as the information page of the
image. It should in particular contain a detailed description of the
content of the image such that vision-impaired users can also
understand what is presented in the image. It may contain structured
markup, such as a table to explain a complex graphic like a statistics
chart. It can also contain the image itself, links back to all the
pages that contain that image, and metadata about the image such as
license and copyright information.

The longdesc IDL attribute must reflect the element's longdesc content
attribute.

Cheers,
Silvia.
