We can also perform binding b/w the XForms model and XForms user interface With bind ATTRIBUTE like that,

Example: I have given you XForms model instance:

<model>
<instance>
<PERSON>
<name> <FNAME/>
<mname/>
<lname/>
</name>
</person>
</instance>
<bind nodeset="/person/name/fname" ID="firstname"/>
<bind nodeset="/person/name/mname" id="middlename"/>
<bind nodeset="/person/name/lname" id="LASTNAME"/>
</model> 
Now, Using bind attribute XForms user interface can bind <input> elements like that:

<input bind="firstname">
<label>First Name</label>
</input>
<input bind="middlename">
<label>Middle Name</label>
</input>
<input bind="lastname">
<label>Last Name</label>
</input>
Using binding we can easily deal with multiple instance model and multiple forms.
