[xquery-talk] Adaptive serialization and indendation

[Joe Wicentowski]

Hi Liam,

Many thanks for this helpful response about the "spirit" of the spec here.
I have one last question - do you have a sense why section 10.1.4 makes
this statement?

> The indent and suppress-indentation parameters are not directly
applicable to the Adaptive output method. [1]

(What throws me off a bit here, of course, is that Adaptive is the only
output method that serializes maps *as* maps, so there isn't anywhere else
to look for direct guidance on indentation of maps.)

I may well proceed with the bugzilla request, but if you have any further
insight on this question, it would help me understand whether the current
phrasing was an unintentional oversight or whether there was some other
consideration that led the WG to state the above.

Thanks again,
Joe
