you can use symbols (as with fields and other widgets)
Is it going to change? Soon? There are comments in the code about
lack of measurement support for XForm - is that the issue and what
that issue is?
unrelated, more a dev note
I have already met that complaints in 3D Annotations support code.
BTW, I am interested in FileAttachment Annotations as a way to
work with 3D models. With LaTeX the main PDF file may contain a 2D picture,
that can be displayed in any PDF viewer, but if you click on it in Adobe
viewer attached PDF file opens with 3D model in it. That attached file
may be produced by some third-party tool, since often such tools output
not just 3D model fit for including in PDF, but a one-page PDF with the
3D model, complex JavaScript to control it (for example to animate it)
and some intarctive text related to the model.
I'm not sure what you mean here. There is some u3d and shockwave
support. (I added u3d because someone asked it but the requester never
tested it). Anyhow, these features are only extended when we (luigi and
me) get proper public test files
Concerning attachments, the next beta will have a new definition model
with inheritance but the \use.. method is still there as well.
The hidden method will not place an annotation. Definition is not really
needed, so a direct \attachment works ok, but a bit of abstraction
(separation between definition and use) does not hurt
% old but stil valid method (consistent with other \use):
%
% \useattachment[test.tex]
% \useattachment[whatever][test.tex]
% \useattachment[whatever][newname][test.tex]
% \useattachment[whatever][title][newname][test.tex]
%
% new method:
%
% \attachment[test.tex]
% \attachment[whatever1][file=test.tex]

Re: [NTG-context] attachment attaches twice - more research
Dear Hans,

i'll patch lpdf-wid but somehow I get the impression that it's more a viewer
issue (the list shown seems to be a merge of filename as well as symbolic
names while a clever list builder should look at the referred objects) ...
but maybe no one else usesvdifferent symbolic names (we had similar issues
with fields in the past and even now advanced field support is somewhat
bugged one or the other way, depending on the viewer version, esp chained
ones)
to say the truth I do not understand what are you talking about :(
The issues I have in mind - separating global attachments and attachments
linked to icons on pages, additional descriptions for attached files -
are addressed in the attached patches.
I am not sure about using attachment lebel as T key, that is indended for
following:
The text label that shall be displayed in the title bar of the annotation’s
pop-up window when open and active. This entry shall identify the user who
added the annotation.
and shows as the upper line when mouse pointer is above attachment icon.
Did not try to have file size and time information added to file stream -
but it'd be nice to have.
Sincerely, Michail
PS. Patches show what I want done, not how it is to be done.

I'll have look at it but not this week (away for a few days). I also need to it with Luigi as he often has torture tests laying around. We also need to keep the a/x standards in mind.
