So does this mean that if the file's timestamp does not change, but the
files's contents change, Subversion will not pick up the changed
contents; svn only looks at the file's contents if the timestamp
changes? No checksum or filesize check, only the timestamp is used to
detect changes?

And according to [3], even if Subversion picks up the file as changed,
it does not pick up the attributes of the file as changed.

Yeah, that's what it looks like. The file's attribues are set when it is
first added, and never changed thereafter.

I am having a similar problem now with directories that need to be
globally readable. This happens because the repository contains a web
site, and the user ('andy') who checks out the repository is not the
user (Apache: www-data) who runs the PHP code. I have created scripts to
handle this but the user has to remember to run the script every time he
does a checkout. AFAIK there is no "svn:writable" property.
I am beginning to see that Subversion manages the CONTENTS of the files,
but does not do well at managing the ATTRIBUTES of the files.
