No, you just have to use different delimiters between and within the
fields. This is why in Ada parameters of a procedure call are separated by
commas rather than spaces.
Though is it about what syntax would be the best? Or is it about how to
parse something in a defined syntax?

Now consider a space between / and >:
<Distance km='3.15'/ >
XML adds here nothing, but a huge readability loss.
