Hello WebAPIers,
as you probably noticed, MathML-3 has published a draft recently.Among the novelties are a section which describes clipboard handling of MathML content. This is the section 7.2:
http://www.w3.org/TR/MathML3/chapter7.html#world-int-transfersBasically, this section describes how a User-Agent should handle the "transfer" (copy, drag,...) of a MathML-expression whose root is the semantics element along with various "annotation" elements as children : each annotation describes an alternate representation of the core expression. UAs that copy such an expression should then copy the alternate representations as an extra transfer-flavour.
An example markup is below.This allows simple markup to contain alternate data-flavours in case things get into the clip-board. These data-flavours may need be requested separately.
I think this offers a way to markup producers to have their users enjoy a rich copy facility, something that I would consider enough for many cases and might replace the clipboard operations specification in its goal... except for input.
For input, maybe there's a simple solution close to a list of flavour- names that a text-field could accept as pasted in?
what do you think?
