I wonder what exactly will it be when everything is unified: {} or
${}? I thought it's the latter, also the issue description seems to
point on this.
The latter one because it's already used in Template and this way new
expressions can be evaluated alongside old ones. This way we can provide
smooth migration path.
As I wrote about in
http://marc.info/?l=xml-cocoon-dev&m=118683052219287&w=2 we already
(since maybe two years ago) has a migration path from the old to the new
syntax. As the string template readers in template is plugable. In that
implementation we actually use {} for the new syntax (following XSLT) as
people seemed to prefer that back then. This is of course not written in
stone, we could use ${} instead if that is what people prefer now. If we
use ${} we more or less have to have JEXL as default expression language
implementation, otherwise it will be highly confusing.
