entityGetPublicIdNull
NIST
The "getPublicId()" method of an Entity node contains
the public identifier associated with the entity, if
one was not specified a null value should be returned.
Retrieve the entity named "ent1" and access its
public identifier. Since a public identifier was not
specified for this entity, the "getPublicId()" method
should return null.
