"""
|
|
Validation values for form fields.
|
|
|
|
Example:
|
|
|
|
<field var='evt.date' type='text-single' label='Event Date/Time'>
|
|
<validate xmlns='http://jabber.org/protocol/xdata-validate'
|
|
datatype='xs:dateTime'/>
|
|
<value>2003-10-06T11:22:00-07:00</value>
|
|
</field>
|
|
|
|
Questions:
|
|
Should this look at the datatype value and convert the range values as appropriate?
|
|
Should this stanza provide a pass/fail for a value from the field, or convert field value to datatype?
