test s1apsetup encode fail

[lester-001]

I have tested two ways to add the IE broadcastPLMNs in the SupportedTAs, but the encoder fail at parsing xml nodes.
the first way:

<SupportedTAs>
    <SupportedTAs>
		<tAC>1</tAC>
		<broadcastPLMNs>
		<broadcastPLMNs>
                       <PLMNidentity>00f110</PLMNidentity>
		</broadcastPLMNs>
		</broadcastPLMNs>
	</SupportedTAs>
</SupportedTAs>

MTS reports this error :
CAUSE: Could not find element null, child of broadcastPLMNs

Complete stack :
java.lang.RuntimeException: Could not find element null, child of broadcastPLMNs

the second way :

<SupportedTAs>
   <SupportedTAs>
		<tAC>1</tAC>
		<broadcastPLMNs>
                       <PLMNidentity>00f110</PLMNidentity>
		</broadcastPLMNs>
	</SupportedTAs>
</SupportedTAs>

the encode is fail in this:
CAUSE: Could not find element broadcastPLMNs, child of broadcastPLMNs

Complete stack :
java.lang.RuntimeException: Could not find element broadcastPLMNs, child of broadcastPLMNs

Here is the ASN.1:

SupportedTAs ::= SEQUENCE (SIZE(1.. maxnoofTACs)) OF SupportedTAs-Item
SupportedTAs-Item ::=	SEQUENCE  {
	tAC					TAC,
	broadcastPLMNs		BPLMNs,
	iE-Extensions		ProtocolExtensionContainer { {SupportedTAs-Item-ExtIEs} } OPTIONAL,
	...
}
BPLMNs ::= SEQUENCE (SIZE(1.. maxnoofBPLMNs)) OF PLMNidentity
