Spry tag delimiter concernt

Question

I have a concern about the use of single curly braces {spry
tag} as Spry tag delimiters within HTML. It is true that one could
use the ISO entitiy characters &123; and &125; where curly
braces occur in literal text. But how do we enforce that for
Contribute users who maintain their own text and may use curly
braces? How do we retrofit existing pages which may include inline
JavaScript with curly braces?
I would prefer to see a distictive multi-character set used
for each Spry delimiter - e.g @@{...}@@ - as is done for
Dreamweaver template parameters - @@(...)@@

Duncan,
I had brought up the idea once of having a form like '${
insert javascript code }' as a way to specify a bit of javascript
to grab a some data from the current row. For example: ${
'{name}'.toUpperCase() }. But I guess ColdFusion (?) uses that
syntax for their stuff, and JSTL does too. Personally, I find
@@(...)@@ a little wordy and I'm sure the inevitable
@@(name)@@@(key)@@ errors will be interesting to track down.
An alternative approach could be a spry:insert tag, so you
could have code like this:
<div spry:repeatchildren="ds">
<span spry:insert="page" />
</div>
and have Spry replace the whole span with whatever the value
for 'page' is in the current row. Obviously, this has the
disadvantage that it wouldn't work in attributes. But you could
solve that with something of the form of this:
<a spry-attr:href="link" />
or
<a href="spry:link" />
The first form, Spry would look for any attributes that start
with spry-attr: and use the second part as the actual attribute to
spit out. The second form is borrowed from Tapestry where they make
use of a prefix in the attribute value to specify that that value
should be treated differently. In this case, it'd look up the value
for link in the current row.
I'd hate to have to code either, but it would offer a way
around the curly brace problem in a generic way that should work
for anything.
