Re: XML Schema

[John Palmieri <johnp martianrock com>]

Well, the DTD's just describe the documents format.  You don't need them per say
unless you want to validate files.  The advantage of XSchemas are that they allow for
data types both complex and simple to be defined.  Actually I am going to use the
simpler Relax-NG stuff.  The great thing about using either one is that they are
easier to read than DTD's and one can write a compiler to create C structures based
on the schema file.  Since it is only used to define the file format and since work
can go on on other parts without having the validator/compiler I don't think that
using them will have any negative impact.  However if you think that having a DTD
around would be good I can do it both ways.
