following features:
Each node can have at most two labels.
The first label gets a special style and is placed on top of the node. In addition,
it cannot be edited once it was created. Instead, a second label is created.
The editing text box has a different background.
Editable Items

Validation
Specifies whether new label texts are validated against the regular expression in the
Pattern field. The default pattern does a simple email address verification.
