The prefixes are namespaces.  xdmp and cts and a few others are 
MarkLogic-specific namespaces holding extension functions.  XDMP stands 
for XML Data Management Platform; CTS stands for Core Text Search.

The sections you're talking about are arbitrary separations designed to 
make reading the docs easier.  You can read about all the functions in 
one go here: http://developer.marklogic.com/pubs/3.2/apidocs/All.html.

The commonly used built-in functions are in the "xdmp" namespace unless 
they're text search specific in which case they're in "cts".  The "fn" 
prefix is the default and isn't generally required.  The other prefixes 
are less used but there to scope library functions together.
