Re: [Xsltforms-support] quicker rendering

[Stephen C. <ste...@gm...>]

Hi Dan,

Its not the model that is the issue in this case but the form itself.

Doesn't the current versions of XSLTForms make use of a browser DOM object
for each model instance? Whereas originally it built a Javascript tree
which was slower.
