OpenSAML user discussion

[Chad La Joie <>]

I'm going to be doing some work with AttributeValue handling this 
weekend.  Here's the root of the problem.  AttributeValue is defined as 
an "any" type and xsi:type is not a required attribute so:

 - If xsi:type is available, the code will attempt to look up the 
needed class (builder/marshaller/unmarshaller) based on that
 - If it's not available, the code will attempt to look up the needed 
class based on the element's name
 - If there still isn't anything available, the code will use the 
ElementProxy classes so that it can at least wrap the content so it's 
not lost.

Given the error you've encountered I'd guess that the attribute value 
you're trying to read does not have a schema instance type attribute and 
that AttributeValue isn't registered or is specifically registered to 
use the ElementProxy element.
