edits to mapping spec.

Can someone please tell me why this text was put in the mapping spec:

[Note 1] User agent should return a user-presentable, localized string
value for the AXRoleDescription.

This was already in the spec:
If performing a text alternative computation for an accessible description,
and the current node provides a descendant <desc> chosen based on the
language rules for the SVG specification; return the description text
alternative an accessible description computation attribute as
presentational.

[Note 2] This specification does not currently contain guidance for when
user agents should fire system alert events. Some guidance may be added to
the specification at a later date but it will be a recommendation (should),
not a requirement (must).

The core specification does this. See Alert and alertdialog:
