Delving into making constraints class methods, we have some tag-
compiler work to do.
Apparently you can say:
<view datapath="${...}" />
or:
<view>
<datapath xpath="${...}" />
In both cases, the constraint really applies to the (invisible)
replication manager, not to the view or the datapath. Right now this
constraint is picked up at run time, ripped off the clone template and
smashed onto the replication manager. That is not going to work in
modern (JS2) runtimes.
I think the right approach here is to have the tag compiler re-write
implicit replication into explicit replication, so:
<view datapath="${...}" />
becomes:
<replicator datapath="${...}">
<view />
</replicator>
etc.
Does this seem feasible? Could we even spit out a deprecation warning
suggesting that explicit replication be used?
