Subversion administrators commonly ask if it is possible
to configure, on the server side, a set of property
definitions which all connecting clients will automatically
consider when operating on working copies checked out from
that server. Unfortunately, Subversion doesn't offer this
feature. Administrators can use hook scripts to validate
that the properties added to and modified on files and
directories match the administrator's preferred policies,
rejecting commits which are non-compliant in this fashion.
(See the section called “Implementing Repository Hooks” for more
about hook scripts.) But there's no way to automatically
dictate those preferences to Subversion clients
beforehand.
