I imagine such a solution:
ComplexComponent.java
@Parameter
@Property
Block titleDecorator;
ComplexComponent.tml
<div>
...
a lot of tags and components
...
<t:decorate by="titleDecorator">
<span id="title">
.. complex content ..
</div>
</t:decorate>
...
a lot of other tags and components
...
</div>
Page.tml
<t:complexComponent>
<t:titleDecorator>
<t:pageLink page="otherPage"><t:decoratedBody/></t:pageLink>
</t:titleDecorator>
</t:complexComponent>
Legend:
decorate - component a little bit similar to delagate
<t:decoratedBody/> - special tag like <t:body/> but relative to
containing Block.
It's a pity, that it is only imagination.
Is it possible to do something similar now?
If not, is it technically possible to make such a improvement in
future versions? It would be very powerful feature.
