XML element names can only contain letters and digits and a few special 
characters such as ".", "-", and "_". The "/" character is one of very 
many characters that is not allowed. You will have to choose a different 
element name. There are an infinite number to choose from, and they are 
all equally "correct". If you are looking for an algorithm that will 
generate a valid element name from any character string, then you could 
consider replacing non-alphanumeric characters with _NNN_ where NNN is 
the numeric value of the Unicode codepoint. It might have been nice if 
the spec designers had allowed numeric character references (&#NNN;) to 
appear in element names, but for some reason they didn't.
