grouped Element

The <grouped> element defines an AVP which encapsulates a sequence of AVPs
together as a single payload. It consists in grouping one or more <gavp> elements.
This way, a single "grouped" element can contain references to multiple AVPs. Each
<gavp>

element holds an AVP name and a vendor-id attribute.

The <gavp> attributes are:

The gavp name attribute must correspond to some existing AVP’s name attribute.

The gavp vendor-id attribute refers to an existing vendor’s id attribute.

Example B–11

, the 3GPP vendor defines an AVP named "CC-Money" which is a

set of previously defined AVPs named "Unit-Value" and "Currency-Code".

Dictionary Extension

Once the Diameter dictionary extension has been defined, use the extendGrammar()
method to apply the extension to the default dictionary as follows:.

//--> Define dictionary extension string

String myDictionary =

<?xml version=\

1.0\

encoding=\

UTF-8\

?>\n

<!DOCTYPE dictionary SYSTEM \

dictionary.dtd\
