My client is the leader in informational genomics - the integration of
bioinformatics with genomics tools to accelerate and improve the drug 
discovery process.

Their solution is developing DNA microarray gene expression information. 
Their technologies and
services permit researchers to fully explore the diverse causes and 
consequences of changes in
gene expression, and to focus on those cellular processes that are 
specifically affected by
exposure to pharmaceuticals, chemicals, or genetic engineering.

The company was launched in 1997 to design and implement DNA microarray 
gene
expression technologies and products and to overcome the severe problems 
that limit the
discovery and effective development of compounds used in the pharmaceutical 
and
agricultural industries. Two years after beginning business, my client 
successfully deployed its first commercially available bioinformatics 
system called "Expression Data Analysis System".
The company's technology and patent portfolio were enhanced by its purchase 
of a
Bioscience company in 1999 thus laid the foundation for a development and 
investment
partnership with a subsidiary company of the Hewlett-Packard Company.

Some folks around here have developed a tool that does
just that. From the documentation:

[[[
<!ELEMENT ROOT (A|B) >

<element name="ROOT">
 <complexType content="elementOnly">
  <choice>
   <element ref="t:A">
   <element ref="t:B">
  </choice>
 </complexType>
<element>

]]]

I think the answer is fairly straightforward, but your
experience shows that it is not obvious. May I ask which
of the specs you have managed to read? Have you
seen the primer?
	http://www.w3.org/TR/xmlschema-0/

Did you use other materials
besides the specs to learn about XML Schemas?

e.g.


The XML Schema Specification in Context
    by Rick Jelliffe, Academia Sinica Computing Centre
    2000-02-24 draft only
	compares XML Schema with XML DTDs, SGML DTDs,
	HyTime, and perl regular expressions

	http://www.ascc.net/~ricko/XMLSchemaInContext.html

Both the DTD->schema tool and the "in Context" discussion
document are linked from our page about XML Schema:
