We recently added a `format` method to the text tag that allows
you to format the content of a text tag using the standard printf-

people with firstName and lastName nodes, you currently would
display each element... [choped]
I vote #2.
Reason: We have xml, javascript and ${foo} syntaxes. It's too much.
<twocents>IMHO ${foo} is a nice hack (I love laszlo contraints) but
I would avoid using it or at least keep use very simple if

That's a good point. Often after building an application, the first
step to optimization is to examine your constraints and replace them
with simpler explicit events. I was thinking the constraint-based
approach was really necessary to take advantage of formatting if you
were not data-binding:
<text
textformat="You have %d items in your cart, for a total of $%6.2d"
data="${cart.itemCount}, ${cart.total}"
/>
But you could re-write that to use explicit events:
<text name="summary" />
<handler name="update" reference="cart">
summary.format("You have %d items in your cart, for a total of $%
6.2d", cart.itemCount, cart.total);
</handler>
I think the question is whether the constraint-oriented syntax is
more helpful for prototyping.
