svn:ignore an existing file

Hello everyone.
I've two question about svn:ignore

1) I've a file that MUST exist in the repository in its "default"
version, but i don't want that people to commit any local change to
it. Is there a way to have this behaviour with svn:ignore?
I mean that with "svn co ..." that file will be checked out as it is
in the repository, but any local change to it will not be included of
any "svn commit ..."

2) If the file i wish to ignore starts with a dot (for example
.myfile) should I use some escaping of the dot in the svn:ignore
property?

Thank You.
