  In betterForm I get this error (after switching ' to " and vice-versa)

xforms-binding-exception: property 'relevant' already present at model item
*URL: *http://127.0.0.1:8080/betterform-trunk/forms/e-letter.xhtml
*Element causing Exception:*/html[1]/head[1]/xf:model[1]/xf:bind[2]
*
*This is not allowed according to the spec and an error should be 
thrown... Personally I always have 2 different XForms processors 
(BetterFORM and Orbeon, but I always use the former)  that I use to 
check if I'm wrong or the engine.

So if Mozilla XForms does not complain, it is in violation of the spec 
(see point 2 in http://www.w3.org/TR/xforms11/#evt-rebuild)

It can be solved by changing it to one bind:

<xf:bind nodeset="stage" relevant="../purpose='ewbrl' or 
../purpose='nibrf'" />

Cheers,

Ronald
