namespace and xsi type in form builder

Rolf
As I have not been able to find pointers in the documentation or email archive
let me post this question:

Using XFORMS it is possible to use namespace and xsi types in instance
definitions and use xpath to refer to the elements in ref and nodeset
references. Eg, I can have <dc:title xsi:type="a" /> and <dc:title xsi:type="b"
/> elements defined in an instance and refer to them using
dc:title[@xsi:type='something'] . See working example in below handcrafted
code.

I am trying to use the same mechanism in form builder ( tried both the
developer version and the nightly build ) but it seems that form builder does
not have gui support for use of custom namespaces and xsi types . Is my
understanding correct or am I overlooking something ?

Thanks,
Rolf Kwakkelaar

Re: namespace and xsi type in form builder

Erik Bruchez

Rolf,

Form Builder binds controls to data using the @bind attribute on
controls and <xforms:bind> elements.

At the moment, Form Builder creates its own flat-ish data structure
when you insert sections and controls. It also inserts <xforms:bind>
elements for all the controls.

What's clearly missing at this point in Form Builder is the ability of
putting your own data model. We hope to improve this in the future
(and it's even better if somebody helps sponsor that!).

But the fact that Form Builder uses binds already gets you halfway
there, as you could:

* create your form with Form Builder
* substitute, by editing the form produced, your own binds @nodeset
expressions pointing to your own data model
* substitute, by editing the form produced, your own form instance

Another option would be to add a translation layer, e.g. in the Form
Runner persistence layer. I.e. you would provide an XSLT
transformation converting between the flat Form Builder format and
your own format and the other way around.
