This spec describes concatenation of node sequences such that they are 
parseable as entities.

In the case you describe I think that fits well.
Atleast in my reading


    5 XML Output Method

This describes serializing a sequence of nodes.  I think this spec would 
fit for your use case.
Atleast that is my read, I admit I have a hard time following the 
reading of this spec (not to blame the authors, I just have a hard time 
understanding it all)
