[XSCH] My review of section 1

Hi Jeff,

I have three comments about section 1 for your consideration:

a) could section 1.3 be entitled "Datatypes in OWL DL"

b) it wasn't obvious to me the relevance of 1.4, after some thought I 
realised that this showed that user defined datatypes do not undermine 
the computational principles of OWL DL, and are suitable for use in 
them. I suggest a further introductory paragraph reminding the reader 
that OWL DL is built on DL theory and that extending OWL DL to use 
user-defined datatypes does depend on further DL theory than that 
presented in the OWL Semantics

c) even so, 1.4 felt a little out of place (relevant but too heavy too 
early), could it be moved to an appendix? e.g. add additional paragraph 
to 1.3 above current last para, explaining that other theoretical work 
is required, and that the appendix gives this work.
