Straight from the AMFPHP code.
AMFSerializer.php (line ~346)
if(isset($d->_explicitType))
{
$classname = $d->_explicitType;
unset($d->_explicitType);
}
AMFPHP uses it on the Serialization side to set the classname and then
unset's the value.

None the less, I am curious how the mechanism works now. In AmfPHP
there is a wrapper that will convert a simple array to a RecordSet
called Arrayf. Among other things it passes the _explicitType
property back. I assume that AS 2, or the flash player then reads
that and casts the data to an instance of RecordSet. It must be this
way as I have never written any parsing engines for returned data
using AmfPHP. Should I assume that the Flash 9 player does this as
well, or more specificaly that the Flash VM for AS3 does this?

code in the Flash Player will create a typed object for a registered
class on deserializing a response. Flex is built on top of
ActionScript so it too relies on the native deserialization behavior
of the Flash Player.

Either way this is a copy of the _remoteClass property mechanism from
Flex 1.0/Flex 1.5 (though note this approach was abandonded in Flex 2.0).

the server side of the equation I am missing.? In the AMF0 payload the
parameter _explicitType is passed.? In AS2 I use Object.registerClass
to map the class writen as a String in _explicitType (ie
"com.renaun.samples.login.vo.BookVO" ) to a AS2 Class found
at?com.renaun.samples.login.vo.BookVO.? What I want to know is if the
parameter _explicitType works in Flex as well?
