Real time Elements of UML

[Ram Dhan Yadav K]

The UML provides four elements to model real time, distributed systems. Referring to this statement , which one of the following is NOT one of these elements?
a) Universal Resource Identifiers (URIs)
b) Time expressions
c) Timing marks
d) Timing constraints
e) Location
It seems e is the answer for this according to Allan.
Well anybody knows resources about this topoic, any illustration and explanations, insight about different choices would be appreciated.
thanks,

I now believe that A is the correct answer. I surfed the web and found references to B,C,D. And I believe location is used in deployment diagrams.
So I would say A.

Where do you use
Timing Expressions
Timing marks
Timing Constratints

Timing Expressions: A time expression is an expression that resolves to a time value.
Timing marks: A timing mark is a denotation of the specific time at which a given event or message occurs
Timing Constraint: A timing constraint is a constraint that involves an absolute or relative value of time

I would assume it's related to Sequence Diagram since these have something to do with timings. Where did you get the idea that my answer is E? Is seems to me that A is the correct answer.

Where are you getting these questions from ??? There has been occasions wherein people have posted a complete test/exam questions and asked for answers and the way i see it , you are posting one question after another - pls explain !

[Ram Dhan Yadav K]

Well,
These questions are from brainbench exam. Theres a free UML exam over there and i guess its a lot useful in consolidating the knowledge.
