upgrade-3.10-1.xsl
Guarantees after this transformation:
* The validate-with attribute of the cib element is set to "pacemaker-4.0".
* All nvset elements are sorted by score within their respective parent
elements (remaining in document order in the case of a tie) and placed below
all non-nvset siblings. Exception: a cluster_property_set with id
"cib-bootstrap-options" always sorts first relative to its siblings.
* Each nvpair has a value attribute. If an nvpair did not have a value
attribute prior to this transformation, it is dropped.
* The crmd-finalization-timeout cluster property has been renamed to
"join-finalization-timeout".
* The crmd-integration-timeout cluster property has been renamed to
"join-integration-timeout".
* The crmd-transition-delay cluster property has been renamed to
"transition-delay".
* The remove-after-stop cluster property is not present.
* The stonith-action cluster property is set to "off" if it was previously set
to "poweroff".
nvset elements include the following:
* cluster_property_set
* instance_attributes
* meta_attributes
* utilization
Any template that matches an element (for example, "primitive") that may
contain an nvset should be placed in a later stylesheet. If such a template is
placed in this stylesheet, its nvsets will not be sorted. We could avoid this
with some refactoring, but it's cleaner this way.

<!--
Copy everything unaltered by default, except sort nvset elements by score.
This doesn't affect behavior. nvset elements of a given type within a given
parent element are processed in order of their score attributes, with a
nonexistent score treated as 0. In the event of a tie, elements are processed
in document order. The sort here preserves document order in the event of a
tie.
The order of nvset elements relative to non-nvset elements does not matter. So
this template puts existing nvset elements after existing non-nvset elements.
This facilitates later transformations, allowing us to more easily drop nvpairs
with unsupported values without changing behavior.
