[oXygen-user] problem validating XML with XSD

[Sorin Ristache]

Hello,

The actions Learn Structure and Save Structure create a DTD, not an XML 
Schema. If I try to associate a DTD with an XML document as an XML 
Schema (.xsd file) using the XML Schema tab of the Associate Schema 
dialog I get the error:

"Could not associate XSD ! - The markup in the document preceding the 
root element must be well-formed."

Are you sure the action Save Structure creates an XML Schema on your 
computer? Did Oxygen display an error in the Errors view when you tried 
to associate the file created by the action Save Structure as an XML Schema?

The line

<?oxygen SCHSchema="VDS.2009-02-11.xsd"?>

is added by the action Associate Schema only if you select the checkbox 
"Embedded Schematron rules" in the Associate Schema dialog but you 
should not do that for a file created with the actions Learn Structure 
and Save Structure because the actions create a DTD which cannot have 
embedded Schematron rules.

The error "Please restart after allocating more memory to oxygen." is 
reported when the size of the opened files is very large and the current 
memory allocated for Oxygen is not enough. You have to increase the 
memory allocated for Oxygen as specified in the error message or 
decrease the total size of the opened files. What is the total size of 
the files that you opened in Oxygen? What action did you do in Oxygen 
when the error was reported?


Regards,
Sorin
