Partitioning on 10g XML DB

Question

Hi, So far I can partition the root element tables. This is through the xdb:tableProps a(see end of post for context). Anyway how do i get the nested tables that it generates to be partitioned as well, the xdb:tableProps is apparently ignored for these.
If this isn't possible how would i genearate a view containing 8 identically defined tables, to give the same apparent functionality as if only the one xml table were being queried. An xsd with the problem for 3 is listed below.
oraxdb:tableProps="partition by range

Answer 1

The view would have to be a union all view, I'm not sure how well XPath re-write would work...
I had writen a union all view to pick from the Parents but how do i write a general view which covers the tables and all their nested tables (and their nest tables nested tables).
Can you help me understand the volume of data you are going to be managing
8,000,000 records in the top tables, there will be an average of 8 nested table rows per parent row foir several items.
the particular benefits you are looking from partitioning in this case...
We get the data from several area sources. Some of these send in a complete refresh of data weekly as opposed to a list of changes. having all the records for an area in the same block will greatly improve times for updates even if we can't blow away and the reload a partition because of the nested tables ( i know this was unavailable with nested tables in 8i )
The option of a clever view could enable swapping by renaming tables in the view which have last weeks data and this weeks already loaded.
Thanks for all help
