In same SU one CSI will be assigned to one component only. If you have
more components and less CSIs then
some components will be instantiated but will not be assigned. Such
components are called spare components.

For binding CSIs to components "objects of Association Classes (chpater
8 B0401 spec)" are need to be defined .
From opensaf samples AppConfig-2N.xml:
<object class="SaAmfCompCsType">
<dn>safSupportedCsType=safVersion=1\,safCSType=AmfDemo1,safComp=AmfDemo,safSu=SU2,safSg=AmfDemo,safApp=AmfDemo1</dn>
</object>
but the association between cstype and comptype of this component should
also exists like below:
<object class="SaAmfCtCsType">
<dn>safSupportedCsType=safVersion=1\,safCSType=AmfDemo1,safVersion=1,safCompType=AmfDemo1</dn>
<attr>
<name>saAmfCtCompCapability</name>
<value>1</value>
</attr>
</object>

Since one csi goes to only one comp in the same SU, such things like a
csi depend on itself does not exist.

In components belong to same comptype achieve instantiation order by
defining saAmfCompInstantiationLevel for each components.
saAmfCompInstantiationLevel never
governs assignment of CSI, this attribute is only for instantiation of
components and not for assignment of CSIs in sa aware components.
