Im new to the dizzy world of xml and schema and have just returned from a four day course in a bit of a daze.
Im just testing out a previously validated xml document and schema on netbeans, which worked well on the course but Im now getting the following error message;
cvc-elt.1: Cannot find the declaration of element 'Books'. 
Any suggestions would be grately appreciated.
As a side issue, can anyone recommend any xml reference books i.e. Dummys guide type thing?
