Here are several off the top of my head:

(1) "feet":

 - One occurrence could be a string that contains the anatomical
condition of a foot, perhaps in a list of body parts in a doctor's form;

- Another occurrence could be a distance;

NOTE: I believe that using an element named "feet" is probably not a
good approach, as it is not sufficiently semantically descriptive -
especially in the second case, which really should be "Distance" (or
similar), with an attribute containing the unit of measure. 

(2) "title":

- One occurrence could be the title of a book;

- Another occurrence could be a title on a house;

(3) "StateCode" - I think this is the best example of the 3

- One occurrence could be a US state;

- Another occurrence (in a scientific context) could be the state of an
element (gasous, etc. - I don't recally the other possibilities)

This third example could very well occur in a domain such as the US
Environmental Protection Agency (EPA).

Hope that helps,
