The first example of a data attribute is data-myajaxlibrary-sort,
which seems in conflict with the example data-datagrid. Would the
trouble in #2 not be about data-myajaxlibrary-datagrid? (Perhaps an
example like data-ms-asp4-datagrid would be more concrete.)

Assuming so, I don't see how such potential markup conflict is that
much different from global variable name conflicts in JavaScript.
While out of scope here, it seems that support for a registry of
prefixes is to support a registry for the JS globals counterparts
(which, for simplicity, ought to be the same).
