Artifact artf5479 : character restrictions in path elements

Tracker:	[CLOSED] JSDL v1.0 Errata
Title:	character restrictions in path elements
Description:	From Marvin Theimer, Microsoft: The main thing I'm after is that the behavior of trying to step "outside" the mountpoint by cd'ing out the top must be either (a) prohibited or (b) explicitly marked as undefined in its behavior, with an error fault potentially being generated. This is because in the Windows world I can imagine that a mountpoint definition might map to setting up a drive letter and you can't cd up out of a drive letter. In fact, I'd be happy enough with the profile stating that paths in JSDL documents should not contain either the "." or the ".." elements at all. That's a fairly strong requirement and guarantees that the job won't fail on systems where your style of semantics are enforced.

Comment:

Added a Security Considerations sub-section to Mountpoint with the following text. 

It must not be assumed that it is possible to step "outside" the mountpoint specified by this ele-ment by, for example, changing directory out the top
. Implementations may choose to prohibit it for security reasons, or it may simply not be possible. For example, on a Unix host it is not possi-ble to
 change directory up out of the root (‘/’), while on a Windows host it is not possible to change directory up out of a drive letter. Behavior is 
undefined.
Implementations may also limit the characters allowed in local paths to prohibit characters such as ‘.’, or ‘..’, etc, which may potentially 
affect the security of the local host.
