I did not think that it would work, but I thought that I would ask. I
know that CVS does not do this either, but their documentation alludes
to the possibility of it working. In the CVS documentation the variable
values are passed into CVS through the -s command line option.

The reason that I want them to get different items is because most of
the items are shared, with only one directory containing user specific
data. This data is user specific. It may be configuration files or
some piece of data that only a specific user should have access to. For
my case where most of the data are shared, it would be easier if I could
specify one svn:externals on a single repository instead of creating 100
different repositories with numerous svn:externals (most of which point
back to the common data).
