It corresponds to the xml schema built-in type "xs:string" - see

It seems to me that I gave some tutorials to the offline software group 
on it back when it was introduced.  For examples, I would propose that 
you look at the file stdhep2hddm.c (in folder stdhep_translators) for 
how to open, write, close an output hddm file.  For input, the programs 
bcal2nt.c and cdc2nt.c are simple examples of how to open a hddm file, 
extract some data from it into a ntuple, and close it.  The structure of 
the functions closely follows the data model hierarchy, you should be 
able to get most of what you need from these simple examples and looking 
at the header file.
