I agree that a standard would promote uniformity. 

On the other hand, adding too many features in a standard will either
prevent innovation 
or the features would simply not be adopted due lack of full generality.

I think 'Save/Restore' functionality falls into this category. I can imagine
a wide variety of mechanisms to allow offline features, including XQuery
support as well. It would be best to keep this as a part of UA property.

Subject: "Suspend and Resume" Mechanism


I'm wondering if any more thought has gone into the specifics of
save-restore? I realize that this will most likely not be included in the
Spec for some time, but I'm curious to read any speculation for a mechanism
as to how this might be accomplished.

I see that XFrames takes a URI string of concatenated attribute-value pairs
[1], and have also seen a cookie approach used, but neither seems
particularly elegant, in terms of the XML context in which XForms operates.
Has anyone discussed other methods of doing this?

I would be very interested in seeing a standardized method making its way
into the Spec.
