Maybe we should have:

				<param name="sequence" quoting="never|auto|outside|replace">master."foo_Account_accountId_seq"</param>

never = hibernate never performs any transform of the data (maybe this should be called "verbatim", the value in XML is what is emitted in SQL)
auto = current and existing behaviour (maybe this should be called "legacy" or "compatibility" ?)
outside = apply SQL dialect specific quote mark to the outside of the value (without modifying the value itself)
replace = substitute hibernate back-tick ` for SQL dialect specific quote mark in pairs of open-close quote so `master`.`foo_Account_accountId_seq` might become [master].[foo_Account_accountId_seq] with some SQL systems that use [] to quote.
