For most applications, yes.  But XML parsing is an issue for the
scalability of high-communication messaging applications.

In one example, it seems people are using XML as an abstraction
between the application and database more and more.  This puts a
strain on the throughput for these types of applications where
database activity is high.

Which is not to say that a binary format would solve this issue, but
it would help.
