/**
* lasso_saml_advice_new:
*
* Creates a new <saml:Advice> node object.
*
* The <Advice> element contains any additional information that the issuer
* wishes to provide. This information MAY be ignored by applications without
* affecting either the semantics or the validity of the assertion.
* The <Advice> element contains a mixture of zero or more <Assertion>
* elements, <AssertionIDReference> elements and elements in other namespaces,
* with lax schema validation in effect for these other elements.
* 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
