XML is extensible. We can add new syntax later without breaking things.
DNS dictates the use of small messages containing public data. No amount

Meanwhile, if the underlying goal behind the use of XML is infinite
extensibility, DNS is a poor choice. Per-user policy statements require
user-keyed lookups (email address instead of domain), future extensions
are likely to require authenticated access, and so forth. Most of all, the
service needs to be able to serve this data reliably and efficiently,
which DNS is unable to satisfy considering its optimizations.
In short, neither DNS nor the goal of extensibility are ultimately
satisfied by trying to force them to work together.
