This type defines the LockFeature operation. The LockFeature
element contains one or more Lock elements that define which
features of a particular type should be locked. A lock
identifier (lockId) is returned to the client application which
can be used by subsequent operations to reference the locked
features.

<xsd:documentation>
The expiry attribute is used to set the length
of time (expressed in minutes) that features will
remain locked as a result of a LockFeature
request. After the expiry period elapses, the
locked resources must be released. If the
expiry attribute is not set, then the default
value of 5 minutes will be enforced.

<xsd:attribute name="lockAction" type="wfs:AllSomeType" use="optional" default="ALL">
<xsd:annotation>
<xsd:documentation>
The lockAction attribute is used to indicate what
a Web Feature Service should do when it encounters
a feature instance that has already been locked by
another client application.
Valid values are ALL or SOME.
ALL means that the Web Feature Service must acquire
locks on all the requested feature instances. If it
cannot acquire those locks then the request should
fail. In this instance, all locks acquired by the
operation should be released.
SOME means that the Web Feature Service should lock
as many of the requested features as it can.
