public static final LinkDataFetchMode SEPARATE
ResultTree.linkDataSource and nodes are separately fetched from the  ResultTree.dataSource. The two fetches are sent together in a
 queue, with the link data fetch first and the separate  node fetch
 second. This makes it possible for your server-side code to use the results of the link data fetch to constrain the node
 fetch (ie, only fetch node information  for nodes that appear in a link)
 
 If this enumerated value is used in a Component XML
 file or server-side DataSource descriptor (.ds.xml file), use the value "separate".
public static final LinkDataFetchMode SINGLE
ResultTree.dataSource, and any duplicated node IDs are
 handled by creating multiple links to a single node. In this mode, the ResultTree.linkDataSource is only used for update
 operations.  Note that the end result of a "single" fetch is exactly the same as fetching link data  and nodes
 separately using "separate" mode; "separate" mode is also conceptually clearer since it emphasises the fact that nodes
 and link data are separate things. We provide "single" mode because, in some cases, it may be more efficient to fetch
 the two types of data together in a single database fetch, using DataSourceField.includeFrom or  some other kind of join
 technique on the server.
 
 If this enumerated value is used in a Component XML
 file or server-side DataSource descriptor (.ds.xml file), use the value "single".
