I'm glad my previous post was helpful.  I use Oxygen with schema valid EAD files with no problems.

Look at your <ead> element in your file.  It should look something like this, which was pasted straight out of a file that successfully validates against the ead.xsd schema:

<ead xmlns= "urn:isbn:1-931666-22-9" xmlns:xlink= "http://www.w3.org/1999/xlink" xmlns:xsi= "http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation = "urn:isbn:1-931666-22-9 ../schemas/ead.xsd" >

Make sure of two things.  First, that the xmlns attribute declaring the xsi namespace comes before the xsi:schemaLocation attribute.  Second, check the content of the xsi:schemaLocation attribute.  The first part should be urn:isbn:1-931666-22-9.  Next, separated by a space, should be the local path of the XSD schema.  If the XSD file is in the same directory then it will just be ead.xsd.  If it is in a parallel directory, which is the case in my example, then it will be something like ../schemas/ead.xsd.  Hopefully this will work for you.

If you have chosen to create RelaxNG schema valid EAD instances, things are a bit more complicated.  There is no formal way of referencing an rng schema from an xml file.  If you do still choose to validate with RelaxNG, then in Oxygen you can use the external validation option, which is represented by the icon in the toolbar that shows a check mark with an ellipsis over it.

Good luck,

I am a relative beginner at using oXygen, and have been working exclusively
with the EAD DTD up to this point.  Now I'd like to work with the schema.
Can anyone give some advice or guidance about getting oXygen to associate a
document with the schema?  I have been working with Michael Rush's helpful
posting from 9/12/2006 and with the dtd2schema.xsl file at the Library of
Congress site for the path configuration; I just haven't licked the oXygen

Thanks for any help you can offer.
