We have a scenario where we will get an Item Id of a particular Component from its parent level. We basically want to know whether that Component is published (in a child Publication), and if it is, we want to republish it.

We are getting these Components (the parent URIs) from `UsingItemsFilterData`, and we observed that the Item XML contains an `IsPublished` attribute, and its value is always **False** *(correct as this item is from the parent level and it cannot be published on that level)*. But this particular Component is published in a child Publication.

So using the parent level Component URI, we need to find out if that particular Component is published or not on a lower BluePrinted level.

We are using SDL Tridion 2011 SP1 and a .Net client application using Core Services.
