Error in Generalization Set labeling

[Paolo F Cantoni]

When you add a Generalization Set to a Generalization relationship AND add a stereotype, BOTH the Generalization Set AND the Stereotype are emitted in the same label.
 
That is questionable (because I'm questioning it , but the bug is actually that the stereotype AND the Generalization Set name are abutted without an intervening whitespace character.  This creates bad formatting and word wrapping.

Please rectify and add intervening whitespace between the two tokens.
