While strolling through the OpenDoc Class Reference recently (just now...)
I noticed (what at first seemed a typo but later...) an unusual (?) argument
"type"ing (?) for lack of a better word...  For example, in the ODObject 
class, there is a method AcquireExtension which has one argument:
"in ODType extensionName".  The method prototype would be:

ODExtension AcquireExtension(in ODType extensionName) ;

The "Discussion" portion of the reference states:  "Your part calls this 
method to obtain a reference to an extension object with the specified 
extension type." Well, okay.  That would (to me) be:

const ODExtension& AcquireExtension(ODType extensionName) ;

What am I missing (alot, I think...)?  What is that "in" type thing at the 
top, anyway? (Note: there are many more methods described in this manner 
throughout the manual, so I doubt that there could be typos...).

Thank you for putting up with such a dumb question...
