WS-Addressing 1.0 Core -- XML infoset representation of EPR > Information model

WS-Addressing 1.0 Core [1] Infoset representation of EPRs (as well as 
the XML 1.0 representation as described/typed by the Schema) allows 
extensibility attributes on the elements:

/wsa:EndpointReference/wsa:Metadata
and
/wsa:EndpointReference/wsa:ReferenceParameters

the Information model equivalent of which are:

[metadata] : xsd:any (0..unbounded)
and
[reference parameters] : xs:any (0..unbounded)

Given that [metadata] and [reference parameters] are collection of 
individual parameters (or elements/EIIs), how/where do the extensibility 
attributes on /wsa:EndpointReference/wsa:Metadata and 
/wsa:EndpointReference/wsa:ReferenceParameters fit in? If not, why is 
the Infoset mapping > Information model?
