> 1) Section 2.4 - Providing XML Instance Data
> This section provides an example of an instance element inside the model

>
> <xforms:model>
>   <xforms:instance>
>     <payment as="credit" xmlns=" http://commerce.example.com/payment
> <http://commerce.example.com/payment> ">
>       <cc/>
>       <exp/>
>     </payment>
>   </xforms:instance>
>   <xforms:submitInfo action=" http://example.com/submit
> <http://example.com/submit> " method="post"/>
> </xforms:model>
>
> What is the format of instanceData produced by form. Is it the same as
that

> or something like this?
> <payment as="credit">
>     <cc>123456789012345</cc>
>     <exp>2001-08</exp>
> </payment>
>
> or something like this?
> <instanceData>
>     <payment as="credit">
>         <cc>123456789012345</cc>
>         <exp>2001-08</exp>
>     </payment>
> </instanceData>
>
> 2) Section 2.5 - Constraining Values
> If the user selects "Cash", does the returned instance data contain the
"cc"
> and "exp" elements?
>
> 3) Is it an expectation that the XForms processor will understand user
> defined data types? For example, if my XForms application uses a class
> called Employee that has two members: a name (String) and an address (a
> nested type), do I have to specify this data structure somewhere? Or is
this
> implicit in instance data, something like this:
>
> <xforms:model>
>   <xforms:instance>
>     <employee>
>       <name/>
>       <address>
>           <line 1/>
>           <line 2/>
>           <city/>
>           <state/>
>           <zip/>
>       </address>
>     </employee>
>   </xforms:instance>
>   <xforms:submitInfo action=" http://example.com/submit
> <http://example.com/submit> " method="post"/>
> </xforms:model>
>
> >From section 2.5, it appears that the data types can be specified in the
> user interface (as constraints). Can they be specified in the model, which
> seems like the logical place to define them?
