Good question.  Here is what the spec says:

"WebCGMString; the Style Property value as a string, or the
empty string if that attribute does
not have an explicitly set value (see the inheritance model for further
related discusion). The value may be a Delimited String."

Based on that, I believe the intention is "empty string" -- you
have never explicitly set the style property (tho' it does have an
inherited value).

IIRC, we had a discussion about this once.  The idea for a flag was
proposed, that would indicate either "explicitly set" or
"effective" value is to be returned.  The first would be
whatever you applied to that node with setStyleProperty() (else empty
string).  The second would be the outcome of applying the
inheritance model of 5.4 (hence a value is always available, i.e., never
returns empty string).

I can't remember our discussion or decision, but apparently the first was
chosen.

Anyone remember more about this?
