AutoCAD .NET :: Filter Multiple Object Types

How to filter multiple object types (here, the swamp, Google, and the docs) and have come up empty handed.  I have code that filters out everything except for blocks (INSERT) with a few additional parameters to exclude blocks of a certain name, but I also need to include MULTILEADERS in the selection filter.

Here is the code I have for the INSERT filter:
 
acTypValAr = New TypedValue() {New TypedValue(DxfCode.Start, "INSERT"), New TypedValue(-4, "<NOT"), _ New TypedValue(2, "BLOCKA,BLOCKB,BLOCKC,BLOCKD"), _ New TypedValue(-4, "NOT>")}

 How to add MULTILEADERS to this selection filter as well?
