Hi Roman,
         I'm not sure why there is a distinction between the two or
why the original AbiWord developers chose to make the distinction. In
general both are used to encode information about a particular document
structure or piece of the document.

In practice properties are used far more often that attributes.

Both defined via "key:value" pairs.

Within the document model these things are just strings and can be any
set of key-value pairs at all. (lives in src/text/ptbl/xp/*.(h,cpp)

The layout engine interprets the key: value pairs and creates the
document you see from them. (Everything in src/text/fmt/xp/*.(h,cpp) )

Cheers

Martin
