localization note annotations and x-its-translate-yes

Hi all (I think especially Yves),

I have two questions about the current XLIFF 1.2 mapping.

First, the value of "x-its-translate-yes" is mentioned for the attribute
'mtype' in a <mrk> element. This value is, however, not mentioned anywhere
in the actual XLIFF 1.2 spec. Is this something planned for 1.3? Is it
something that will be added via the itsxlf namespace? This is more
curiosity than practicality.

Second, localization notes are supported via the <note> element, but the
document only mentions the use of general <note>'s. The default value for a
<note> element's 'annotates' attribute is "general". The other possible
values are "target" and "source", indicating that the note applies either
to the <source> or the <target> element contents. Is this to be supported,
as well? By which, of course, I mean, is it recommended that implementers
support this or is it to be ignored?
