Re: [Xsltforms-support] quicker rendering

[Dan M. <dan...@gm...>]

Hi Stephen,

One alternative I might suggest is to use a "multi-tab" form and use a
technique called "incremental model loading" if your model is large.

Here is a demo of incremental model loading:

http://en.wikibooks.org/wiki/XForms/Incremental_Model_Loading

here is some sample UI for the tabs:

The tricky part comes if you have bind rules that span tabs.
