These are examples of names of properties that you *could* invent for

Subversion doesn't preserve permissions or ownership information; it
simply provides a generic metadata mechanism for users to exploit
however they wish.

Ben Reser, I believe, has written a script to do what you're looking
for: when you run it, it "stores" filesystem metadata in the properties
before committing, and also has the ability to read the metadata and
apply it to the files again.

Correct. The svn:executable property makes a file executable. It's the
only sort of permission that svn can understand, because permissions are
inherently un-portable from one OS to another.
