<p>This is far from the final word on injection and disambiguation; we'll be
coming back to this concept repeatedly. And in later chapters of the cookbook,
we'll also go into more detail about the many other concepts present in this
example. The important part is that Tapestry <em>primarily</em> works off the
parameter type (at the point of injection), but when that is insufficient
(you'll know ... there will be an error) you can provide additional
information, in the form of annotations, to straighten things out.</p>
