Subject: [xacml] change request: xacml context attributes and data types

Currently <xacml-context:Attribute> element 
allows DataType attribute.
 
Rationale for keeping DataType attribute in the 
<xacml-context:Attribute> element was that
it can sometimes be helpful, such as specifiying 
subject-id format, like
subject-id="cn=simon", 
data-type="x500-name"
 
But this information is redundant, because 
subject-id attribute will be passed to the specific
function that expects arguments of certain type. 
For example, if subject-id is passed to
the x500Name-equal function it expects it's 
arguments to be in x500 name format.
 
So data type does not add value here.
 
Another problem is that we can not access DataType 
attribute with AttributeDesignator.
 
Proposal: remove DataType attribute from the 
<xacml-context:Attribute>.
