I'd be worried if you're writing XML for which a valid DTD cannot be
produced...

Not automagically.

I have a generic package that I'm using which takes in a type, an
array of strings to represent the elements/propertys, and getproperty
and setproperty methods for that type which the set takes two strings
(the name of the property and the value to set it too) and the get
function takes one string (the name of the property) and returns a
string.

Read and Write functions are provided that utilise the passed in
methods, using the SAX parser in XML/Ada. It's not pretty, it's not
big and it's not clever, but it's easier than writing custom parsing
procedures every time. All the programmer has to do is the switch
statements in the methods to translate from strings to the appropriate
type and back again. Works nicely for the one-record-per-file
structure I tend to have.
