* The <Advice> element contains any additional information that the issuer

* The <Advice> element contains a mixture of zero or more <Assertion>

* Following are some potential uses of the <Advice> element:
|
|
*
|
|
* - Include evidence supporting the assertion claims to be cited, either
|
|
* directly (through incorporating the claims) or indirectly (by reference to
|
|
* the supporting assertions).
|
|
*
|
|
* - State a proof of the assertion claims.
|
|
*
|
|
* - Specify the timing and distribution points for updates to the assertion.
|
|
*
|
|
* Return value: the new @LassoSamlAdvice
