My name is Ariel Gertzenstein. I am working at the
Georgia Institute of Technology on translating a
manufacturing file to XML format.
In the manufacturing spec there are some complex BNF
productions that are used several times. For example:
<complex_BNF> ::= <elem1>,<elem2>,...,<elem25>

One approach I can take when making the XML Schema is
to build a new element for this complex_BNF. And have
an element reference to this new element for each
appearance of the BNF production. This would reduce
the size of the XML Schema but there is going to be a
new XML tag for the complex_BNF_production, and this
name was not supposed to be in the original
manufacturing file.

Another approach is to have a super-type containing
all the attributes and elements of the "complex_BNF".
This type would be inherited by all the element types
which refer to the complex_BNF_production.
My question is: how do I specify the order of elements
inside a type which has local elements and inherited
elements. How can I use order=all for all the
elements? Which elements go first, the local or the
inherited ones?

Another approach I was thinking is to have a separate
file for each complex BNF production. And have it
included with an INCLUDE tag. But can INCLUDE tags be
put anywhere in the XML Schema?

The really better way to do this would be to be able
to use some kind of MACRO (something like DTD's
entities). This way I could replace one word with a
lot of elements.

Thank you very much,
Ariel Gertzenstein.
