Each form has a group of
that specifies the user interface for the model:
<input xmlns="http://www.w3.org/2002/xforms" model="p1" ref="/doughnuts/quantity"> <label>Quantity</label> </input>
There can (and generally will be)
be more than one
input element in the group.
The group can appear anywhere in the XHTML document, interspersed with other markup.
The browser updates the model as the user fills in data.
The browser checks the data the user enters against the schema.
