<imm:IMM-contents>
<class name="TestFlag">
<category>SA_CONFIG</category>
<rdn>
<name>testFlag</name>
<type>SA_STRING_T</type>
<category>SA_CONFIG</category>
<flag>SA_INITIALIZED</flag>
</rdn>
<attr>
<name>notify</name>
<type>SA_STRING_T</type>
<category>SA_CONFIG</category>
<flag>SA_WRITABLE</flag>
<flag>SA_NOTIFY</flag>
</attr>
</class>

~~~
2.Create an object having a size of value over ~65000 characters by using this
script
