Ethan et al.,
Is inherited metadata cumulative?
In this example:
<dataset name="level1" ID="SingleFileWcs">
<metadata inherited='true'>
<serviceName>dap</serviceName>
<property name="foo" value="bar"/>
</metadata>
<dataset name="level2" urlPath="wcs/foo" ID="wcs/foo">
<metadata inherited='true'>
<serviceName>wcs</serviceName>
<property name="dude" value="ranch"/>
</metadata>
<dataset name="level3" urlPath="wcs/foo" ID="wcs/foo" />
</dataset>
</dataset>
Does the dataset "level3" have the services "dap" and "wcs"?
Does the dataset "level3" have the properties "foo" and "dude"?

Ethan,
Along the same lines then, can <access> elements be inherited? Or is
it bound only to the containing dataset and never to that dataset's
children?
Example:
<dataset name="level1" ID="SingleFileWcs">
<metadata inherited='true'>
<access serviceName=dap />
</metadata>
<dataset name="level2_a" urlPath="wcs/foo" ID="wcs/foo" />
<dataset name="level2_b" urlPath="wcs/foo" ID="wcs/foo" >
<serviceName>otherService</serviceName>
</dataset>
</dataset>

Another question, about service inheritance.
Example:

<serviceName>dap</serviceName>
<dataset name="level2_a" urlPath="wcs/foo" ID="wcs/foo" />
<dataset name="level2_b" urlPath="wcs/foo" ID="wcs/foo" >
<serviceName>otherService</serviceName>
</dataset>
</dataset>
Is the dataset "level2_a" associated with the "dap" service??
No. Though it would be if the "dap" serviceName element were
enclosed in
an inherited metadata element, like this
<metadata inherited='true'><serviceName>dap</serviceName></metadata>
Is the dataset "level2_b" associated with the "dap" service??
No. Not even if the "dap" serviceName was inherited, because the
"otherService" association overrides any inherited association.
Is the dataset "level2_b" associated with the "otherService"
service??
Yes, it is.
