[Zope] (tal, metal) macro template id

[Pablo Ziliani]

Hi all,
Inside the template where macros are defined, I need to get its id, i.e:

<span metal:define-macro="kk">
  Showing: 
  <b tal:content="template/getId"> conextual! </b>
  contents, rendered inside page
  <b tal:content="thisMACROpage/getId"> fixed / ??? </b>
</span>

Any hint?

Thanks in advance,
Pablo
