When using AJAX to dynamically request small pieces of a page, there is
a need for a number of small components that would handle those
requests.  Since components are small it would be preferable to pack
them as sub-components of a single component instead of creating a file
per a component:

lib.ecpp:
-------------------------------------------------------------
<%def comp1> ... <%/def>
<%def comp2> ... <%/def>
<%def comp3> ... <%/def>
...
-------------------------------------------------------------

At the moment the only way to call sub-components directly from a page
that I am aware of is to pass the name of a sub-component as a parameter
of a request:

/lib?sub=comp2

My lib.ecpp, ignoring error handling, would look like this:
-------------------------------------------------------------
<%args>
  sub;
</%args>

% std::string lib("lib");
<& (lib + "." + sub) >

<%def comp1> ... <%/def>
<%def comp2> ... <%/def>
<%def comp3> ... <%/def>
...
-------------------------------------------------------------

Does anyone else use similar technique?  Are there other ways to call
sub-components from a browser?

Thanks in advance,
Yuri
