When the test is true, this will cause the fieldspace associated with the form to be reinitialized at the point that this tag is dropped. The code contained by the tag may contain setup code of some sort, but may also contain messages to print to the user, etc. It is regular MIC code. This tag's purpose is to refresh the fieldspace when actions on the current page have changed the nature of the data. For instance, if a user asks that certain items in a dynamic field be deleted, and the page is refreshed, then we must first instantiate the regular fieldspace and delete the fields. But, if we did not re-initialize, there might be blank items on the screen. And, depending on how initialization works, there is the possibility that a field will be missed since the data may collapse on the next page, and the item between the final on the current and the first on the next will never get shown.
