[oslc-core] Provided guidance for adding relationship labels

[Steve K Speicher]

I wanted to call out some specification updates that was created for 
handling of relationship labels on URI relationship properties.  Note the 
support for this is optional but wanted to make sure this was done in a 
uniform way across implementations.  Let me know if there are any issues 
with this.
