Dynamic Semantics of Document

Hi,

Few days ago, I read some articles about MSOffice 2007, and I was puzzled with the term: Dynamic Semantics of Document.

Can anybody explain the term: Dynamic Semantics of Document in MSOffice.

Is there any tutorial or material about this topic?

Thank you in advance!
