Element cmd has an attribute name which is invalid: “tac+” is an invalid value.
is there any way i can do this??

Seems like this is not possible. The name (from ConfD User Guide - section clispec) is of type:

/clispec/$MODE/show/callback/mode/name (xs:NCName)

The NCName has restrictions. Eg. from here http://stackoverflow.com/questions/1631396/what-is-an-xsncname-type-and-when-should-it-be-used:

“The practical restrictions of NCName are that it cannot contain several symbol characters like :, @, $, %, &, /, +, , ;,
whitespace characters or different parenthesis. Furthermore an NCName
cannot begin with a number, dot or minus character although they can
appear later in an NCName.”
