Something like this:
<!-- Use attribute fbar for simple "fbar : x" if present.
Use fbar: { ..} if only one contained tag,
Use fbar : [ ... ] if more than one contained tag
-->
<def tag="ext-FooterBar">
fbar:
<if test="&fbar"><%= fbar %></if>
<if test="&if parameters.default.size == 1"><ext-object
param="default"/></if>
<if test="&if parameters.default.size > 1"><ext-array
param="default"/></if>
<%= "," if !last_item? %>
</def>
<def tag="ext-items">
items:
<if test="&items"><%= items %></if>
<if test="&if parameters.default.size == 1"><ext-object
param="default"/></if>
<if test="&if parameters.default.size > 1"><ext-array
param="default"/></if>
<%= "," if !last_item? %>
</def>
<def tag="ext-array">
[ <do param="default"/> ]
<%= "," if last_item? %>
</def>
<def tag="ext-object">
{ <do param="default"/> }
<%= "," if last_item? %>
</def>

But this approach also seems to lead to a lot of duplication, not very
DRY! What should I do to make it DRY?
