title: SQL 2008 HierarchyID with Multiple Root Nodes
body: <p>I wanted to use the new HierarchyID type in SQL Server 2008 to handle the page relations in a small wiki application. However It would need to have multiple root nodes since every main article/page per account would be a root node. </p>
  
  <p>From what I have read the HierarchyID type only allows 1 root node per column is this correct? and is there any way to enable multiple root nodes ? </p>
