> The current format for specifying queue placement rules in the fair scheduler allocations
file does not lend itself to easy parsing via a JAXB parser. In particular, relying on the
tag name to encode information about which rule to use makes it very difficult for an xsd-based
JAXB parser to preserve the order of the rules, which is essential.
