  namespace that it sets aside for its own use. And Subversion
  does, in fact, use properties, both the versioned and
  unversioned variety. Certain versioned properties have special
  meaning or effects when found on files and directories, or house
  a particular bit of information about the revisions on which
  they are found. Certain revision properties are automatically
  attached to revisions by Subversion's commit process, and carry
  information about the revision. Most of these properties are
  mentioned elsewhere in this or other chapters as part of the
  more general topics to which they are related. For an
  exhaustive list of Subversion's pre-defined properties, see
  the section called “Subversion properties”..

The repository administrator can setup methods to protect against this loss, and by default, modification of unversioned properties is disabled.

  Subversion also provides, via its runtime configuration
  system (see the section called “Runtime Configuration Area”), a more
  flexible automatic property setting feature which allows you
  to create mappings of filename patterns to property names and
  values. Once again, these mappings affect adds and imports,
  and not only can override the default MIME type decision made
  by Subversion during those operations,.
