This is correct, Sam. Word has all of these structures to save data.
Basically, they have a concept of a SPRM (single property modifier). A SPRM
is contained in a GRPPL (group of property modifiers). Basically, a SPRM is
a mask to tell you what field in a structure to change and the changed
value. So Paragraph Properties (PAPs) are stored as Diff's to PAPs (PAPXs)
and save something like 50x the size.
Text is not compressed however. Word's "fast save" format results in even
larger files...
