[Standards] Meta-data in Pubsub XEP-0060

[Brett Zamir]

Might the meta-data query result (section 5.4 in XEP-0060) recommend the 
@type attribute on the <x>'s <field/> children so that a client could, 
for example, know to display a boolean type as the more readable "true" 
and "false" as opposed to the potential values of 1 and 0?
