you can use symbols (as with fields and other widgets)

unrelated, more a dev note

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]
% \attachment[whatever2][file=test.tex,method=hidden]
% \attachment[whatever3][name=newname,file=test.tex]
% \attachment[whatever4][title=mytitle,name=newname,file=test.tex]
% indirect
% \defineattachment[whatever5][file=test.tex] 
% \defineattachment[whatever5][file=test.tex,method=hidden] 
% direct (no definitions)
% \attachment[test][file=oeps.tex,title=Oeps,author=Hans,subtitle=TeX 
% autolabel:
% \attachment[file=oeps.tex,title=Oeps,author=Hans,subtitle=TeX 
% % \setupattachments[\c!symbol={symbol-normal,symbol-down}]
