AXI locked access

Does a locked request on either the read or write channel cause both channels to be locked? For example, one master request a locked write transaction to a slave, the read channel also will be locked? if both channels have been locked, whether a read unlock  access also can complete the whole locked sequence?

    In spec 8.5 The order in which a slave receives the first data item of each transaction must be the same as the order in which it receives the addresses for the transactions.

    It does not tell the master must assure this or the interconnect must. If the master dont need obey this, the interconnect will buffer a lot of data.
    For example, if a master requests 4 write transactiona and all accept by slave, but master sends the first data of first transaction after it sends all other 3 transaction's data. Now the interconnect need buffer all this 3 transaction's data.
