Bug 34286

TxXMLFileDescriptorsStore
TxFileContentStore

The above are useful in a production environment to generate and continue to add
data to a Slide Store. However, once a Slide Store is 'closed' (i.e. Slide Store
for only one year, like 2004) no way to access this Slide Store from a read-only
medium like CD/DVD.

Recommend a new RoXMLFileDescriptorsStore and RoFileContentStore optimized for
read-only access that the above Tx* versions can easily be exported or swapped
to use.

Also reference Bug # 31756 related to Scope/URI binding seperation directly
related to moving stores to CD/DVD, but not a dependency.


Sample error accessing a TxXMLFileDescriptorStore from a read-only CD that
should be corrected by this bug. Note FileOutputStream error where the Tx* store
is trying to write to the files.def.xml file:
