Wouldn't you use slots?

<div metal:define-macro="widget_1_view">
  I am the widget 1 view on <span metal:define-slot="content"/>.
</div>

Used like

<div metal:use-macro="here/widgetlib/macros/widget_1_view">
  <span metal:fill-slot="content" tal:replace="here/getId"/>
</div>

Assuming here/getId = "WidgetsForAllPeople"
Produces:

<div>
  I am the widget 1 view on WidgetsForAllPeople.
</div>

Or something similar.

But I'm not really sure what you are trying to do...
