To get data from outside input, reshaped as needed.

Admins, operators, ...  They use their preferred, but customized
to your grammar, XML editor that (a) lets them write consistent
configurations and no others and (b) uses XML behind the
scenes only.   (Much better than information nicely
scattered in some Excel sheet.  Better than some
proprietary system dependent GUI for config making
as these seem to have a limited life time built in.)

> Who does read it?

The middleware.  Your middleware program will process
the XML data produced by outsiders during STEP 1 above.
Wouldn't this processing step resemble an integration
build with regard to the state of compilation
units (XML documents) where a compiler (validating XML parser)
has seen the units?
(STEP 2)

STEP 4:
You have valid data ready for consumption as is...

Otherwise, there is a problem with input sent to you,
and caused by something outside your responsibility.
