	<cfwddx
		action="string"

		[output="string"]
		[toplevelvariable="string"]
		[usetimezoneinfo="boolean"]
		[validate="boolean"]
		[xmlconform="boolean"]>
	
This tag is also supported within cfscript
	<cfscript>
		wddx
		action="string"
		input="any"
		[output="string"]

Attributes

The attributes for this tag are fixed. Except for the following attributes no other attributes are allowed.
Name Type Required Description
action string Yes Specifies the action taken by the cfwddx tag. 
input any Yes The value to be processed. 
output string No The name of the variable to hold the output of the operation. This attribute is required for
action = 'WDDX2CFML'. For all other actions, if this attribute is not provided, the result of the
WDDX processing is outputted in the HTML stream. 
toplevelvariable string No The name of the top-level JavaScript object created by the deserialization process. The object
created is an instance of the WddxRecordset object, explained in WddxRecordset Object. 
usetimezoneinfo boolean No Indicates whether to output time-zone information when serializing CFML to WDDX. If time-zone
information is taken into account, the hour-minute offset, as represented in the ISO8601 format, is
calculated in the date-time output. If time-zone information is not taken into account, the local
time is output. The default is Yes. 
validate boolean No Applies if action = "wddx2cfml" or "wddx2js".
- Yes: validates WDDX input with an XML parser using
WDDX DTD. If parser processes input without error,
packet is deserialized. Otherwise, an error is
thrown.
- No: no input validation 
xmlconform boolean No if set to true generate valid xml, if set to false (default) the xml generated is compatible to other engines, but not valid xml (use for example single quotes for attribute values)
