XForms Data Types
The XForms model supports XML Schema data types.
XML Schema Data Types
The XForms model supports XML Schema data types. This feature allows the XForms processor to check the data for correct input values.
You can learn more about XML Schema in our XML Schema tutorial.
To use XML Schema data types, you must add the XML Schema namespaces to your namespace declaration like this:
<html
xmlns:xf="http://www.w3.org/2002/xforms"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> |
After adding the XML Schema namespaces, you can add type attributes to your XForms instance elements like this:
<xf:instance>
<person xmlns="">
<fname xsi:type="xsd:string"/>
<lname xsi:type="xsd:string"/>
<born xsi:type="xsd:date"/>
<size xsi:type="xsd:integer"/>
</person>
</xf:instance> |
XForms supports all XML Schema data types, except:
- duration
- ENTITY
- ENTITIES
- NOTATION

Binding Datatypes
In XForms you can also use the <bind> element to associate data types with instance data:
| <xf:bind nodeset="/person/size" type="xsd:integer"/> |
