This annex describes how to create an extended schema. How to create “IP address of Mobile IP home agent” is used as an example.
It is possible to support an Extended Schema without defining additional IEs or TLVs (including vendor specific ones) other than those that are defined in this standard. An extended schema can be defined as an XML document. An example Extended Schema definition is shown as follows.
"This attribute indicates whether make-before-break handover is supported. A value of true indicates that make-before-break handover is supported. A value of FALSE indicates that make-before-break handover is not supported."
