My implementation behaves the same as 'svn export' in all of the above
situations.

I am getting 'svn:externals' property from svn_ra_get_dir2() and parsing it
with 'svn_wc_parse_externals_description3()' . For each external item,
it will contact
the external item URL and list contents from there.

Some other implementations of externals are using
svn_wc__externals_gather_definitions() to get externals information from
a WC path.
Can we use this function to read externals from a WC path or we should
always get
externals information from repository for a given path or URL?

Thanks & Regards,
