property – a property of type IList that is to be iterated over (required)
open – the string with which to open the entire block of iterations, useful for brackets (optional)

Table 3.10. Creating a list of conditional clauses
Element	Description


<iterate>	Iterates over a property that is of type IList Example Usage:
<iterate prepend="AND" property="UserNameList"
  open="(" close=")" conjunction="OR">
  username=#UserNameList[]#
</iterate>
Note: It is very important to include the square brackets[] at the end of the List property name when using the Iterate element. These brackets distinguish this object as an List to keep the parser from simply outputting the List as a string.
