2.15.3 TAS³ Control and Reporting Points

The status messages can emanate from several parts in TAS³ security layer, or even from points inside the application. To assist in determining where errors originate, the <tas3:Status> element carries a ctlpt XML attribute, whose value is a URI identifying the origin of the error. While application can define a number of additional URIs, the TAS³ architecture defines the following:

urn:tas3:ctlpt:pep:rq:out

Request Out PEP (callout 1)

urn:tas3:ctlpt:pep:rq:in

Request In PEP (callout 2)

urn:tas3:ctlpt:pep:rs:out

Response Out PEP (callout 3)

urn:tas3:ctlpt:pep:rs:in

Response In PEP (callout 4)

urn:tas3:ctlpt:app

Application. In this case application can also define its own URIs.
