I'm not sure that describing the third Monday in February is required
for the purposes of the standard under discussion, but the MARC 21
Format for Holdings Data attempts to do this for the purpose of
recording and predicting publication patterns of periodicals. It's
fairly inscrutable and I wouldn't necessarily recommend it for this
standard. It can be found at
http://www.loc.gov/marc/holdings/hd853855.html under subfield $y.
The third Monday in February would be described as w0203mo.

Subject: Re: Requirements // Ordinal and Week dates
Once again I ask for an explanation of the requirement.
I have two areas of confusion.
First, the recent examples include, for example, "3rd Monday in Feb.
Is this a real example? The third Monday in February of 2011 is a real
and can be represented as "2011-02-21". I had thought that you wanted
represent "third Monday in February", independent of year, in order to
represent a pattern, as in this case a particular US holiday, i.e.
Washington's Birthday, falls each year on the third Monday in February.
Second (as Bruce has already asked) assuming you want to represrent
Monday in February" why can't it be represented as the human readable
'third Monday in February', or '3rd Mon. in Feb'; i.e. why does it need
be normalized for computer readability? Can you provide a use case
machine readability is necessary?
