[Metadatalibrarians] Namespace problems

[Clay Redding]

Hi Greta,

I think your namespace declarations are fine, as long as you've  
declared the OAI namespace in the xsl:stylesheet element.  You can  
generally put it anywhere, but I tend to declare my namespaces  
globally at the root xsl:stylesheet element.

It appears that the error the validator is throwing says that  
<oai:record> is appearing as the first child in the modsCollection  
wrapper, which will result in an invalid instance, since <mods> is  
the only child allowed under <modsCollection>.  Typically, the  
correct structure is to have <oai:record>, and then your MODS  
instance within that.

If you'd like, feel free to send along your XML and XSL and we can  
help you troubleshoot.
