Professor, I tried to apply the pair 

 http://www.cs.umb.edu/~ram/tmp/xhliu1.xml
 http://www.cs.umb.edu/~ram/tmp/xhliu1.xsd

on http://www.w3.org/2001/03/webdata/xsv. It give me the warning messages:

http://www.cs.umb.edu/~xhliu1/XMLDir.xsd:3:34: Warning: attempt to
overwrite type {None}FileType, ignored

http://www.cs.umb.edu/~xhliu1/XMLDir.xsd:6:27: Warning: attempt to
overwrite type {None}DirectoryType, ignored

http://www.cs.umb.edu/~xhliu1/XMLDir.xsd:17:20: Warning: attempt to

overwrite element {None}Directory, ignored

http://www.cs.umb.edu/~xhliu1/XMLDir.xsd:27:61: Warning: attempt to
overwrite element {None}File, ignored

I think the problem is that I specified the
xsi:noNamespaceSchemaLocation="http://www.cs.umb.edu/~xhliu1/XMLDir.xsd"
in my XML document, therefore, the validator will automatically take 
http://www.cs.umb.edu/~xhliu1/XMLDir.xsl as the X-schema location. But in
the validation, I apply http://cs.umb.edu/~ram/tmp/xhliu1.xsl as the
x-schema doc, there is a duplication. Therefore, there are some warning
messages about http://www.cs.umb.edu/~xhliu/XMLDir.xsl, not about
http://www.cs.umb.edu/~ram/tmp/xhliu1.xsl. (actually both files are same ,
just in different location). If you only apply to
http://www.cs.umb.edu/~ram/tmp/xhliu1.xml, and the validator will
automatically locate the x-schma, and there is no warning messAage.

I can not see why 'ExecutablePermission' is not a valid NCName.

Thanks!
