XForms Namespace
You should use an XForms namespace in HTML and XHTML 1.0.
But hopefully not in XHTML 2.0.
The XForms Namespace
The official namespace for XForms is: http://www.w3.org/2002/xforms
If you want to use XForms in HTML (or XHTML 1.0), you should declare all XForms
elements with an XForms namespace.
XForms is expected to be a standard part of XHTML 2.0, eliminating the need
for the XForms namespace.
This example uses the XForms namespace:
<html xmlns:xf="http://www.w3.org/2002/xforms">
<head>
<xf:model>
<xf:instance>
<person>
<fname/>
<lname/>
</person>
</xf:instance>
<xf:submission id="form1" method="get"
action="submit.asp"/>
</xf:model>
</head>
<body>
<xf:input ref="fname">
<xf:label>First Name</xf:label></xf:input>
<br />
<xf:input ref="lname">
<xf:label>Last Name</xf:label></xf:input>
<br />
<br />
<xf:submit submission="form1">
<xf:label>Submit</xf:label></xf:submit>
</body>
</html>

In the example above we have used the xf: prefix for the XForms namespace, but you are free to
call the
prefix anything you want.
