Hi surajit,
    First of all I think it's impossible to have the XSD datatype there
except if you declare it additionally. We can have a property that maps
ot:Parameter-type individuals to XSD datatype URIs or we can subclass
ot:Parameter and introduce ot:StringParameter etc. Instead, I would ask
what is the purpose of having the datatype in there. And the answer is,
to provide information to the client regarding the expected type for the
particular parameter. This however can be retrieved by an OPTIONS on the
resource  (see latest ontology update and specification for OPTIONS).
We've already implemented this method for most of our resources.
RDF-formatted OPTIONS can even lead to automatically generated web
interfaces for web services!

Evaluated runtime is not a parameter in the OT sense as it is not
something expected by the client as input. This can be assigned to your
node using some other ontological property (e.g. ot:evaluatedRuntime) or
you can include it only in HTML representations and not in RDF.

Best regards,
Pantelis
