V.next: attribute value templates

I expect attribute value template are uncontroversial, but...

Can they refer to a context node?

If they can, what is the context node? The document on the default readable port?

Can they be used for elements that would ordinarily be resolve statically?

<p:pipeline>
  <p:option name="method" required="true"/>
  <p:serialization port="output" method="{$method}"/>
  ...

                                        Be seeing you,
                                          norm
