Non supported implicit references in Spring application context

Here are few scenarios where the implicit references/properties does not work in Tuscany.....

Scenario 1: (For contructor-arg elements whose type attribute is absent)

<constructor-arg><ref bean="savingsAccountService"/></constructor-arg>
<constructor-arg><ref bean="stockAccountService"/></constructor-arg>

Scenario 2: (Injection through Collections)
<bean id="moreComplexObject" class="example.ComplexObject">
<!-- results in a setAdminEmails(java.util.Properties) call -->
<property name="adminEmails">
<props>
<prop key="administrator">administrator@example.org</prop>
<prop key="support">support@example.org</prop>
<prop key="development">development@example.org</prop>
</props>
</property>
<!-- results in a setSomeList(java.util.List) call -->
<property name="someList">
<list>
<value>a list element followed by a reference</value>
<ref bean="myDataSource" />
</list>
</property>
<!-- results in a setSomeMap(java.util.Map) call -->
<property name="someMap">
<map>
<entry>
<key>
<value>an entry</value>
</key>
<value>just some string</value>
</entry>
<entry>
<key>
<value>a ref</value>
</key>
<ref bean="myDataSource" />
</entry>
</map>
</property>
<!-- results in a setSomeSet(java.util.Set) call -->
<property name="someSet">
<set>
<value>just some string</value>
<ref bean="myDataSource" />
</set>
</property>
</bean>
