RE: Xml Schema profile

We ran a similar study last year with 60+ industry schemas and if I remember correctly we found that substitution groups are used in 20% of schemas.  The results of the study were presented at Xml 2005 and are available at http://www.idealliance.org/xmlusa/05/call/xmlpapers/49.1704/.49.html

Add XBRL (eXtensible Business Reporting Language) / http://www.xbrl.org to
that list. It makes EXTENSIVE use of substitution groups and has done so for
a number of years.

Thanks

I was also somewhat surprised seeing this assumption. I did a quick search
on our XML Schema repository which brought up the following well-known
schemas besides the opengeospatiol.org's ones (GML, etc.):

OVAL (Open Vulnerability and Assessment Language) / http://oval.mitre.org
FpML (Financial products Markup Language) / http://www.fpml.org COLLADA
(COLLAborative Design Activity) / http://www.collada.org HR-XML /
http://www.hr-xml.org
