[Zope] ZPT idiom

[Jim Penny]

Speaking of idiom:

which do people feel is better:

<input name="test" tal:attributes="value request/foo">
or 
<input name="test" value="dummy" tal:attributes="value request/foo">

That is, should the value= tag be given when it is going to be replaced
by a tal?  (Both forms work, I am concerned about readability and 
pedagogy.)

What about

<input type=checkbox name=test2 
  tal:attributes="checked request/foo | nothing">
vs.
<input type=checkbox name=test2 checked 
  tal:attributes="checked request/foo | nothing">

Again, both forms have been tested, does the latter form help or hinder
readability?
