Paul Foxworthy commented on OFBIZ-6807:
---------------------------------------
schemaLocation and noNamespaceSchemaLocation are hacks. It is silly to expect
an XML document to know the right place for its schema. So its good that you
removed schemaLocation from the webapp files.
However, there are still thousands of noNamespaceSchemaLocation in other XML
files.
What the XML files *should* have is a namespace. Then external tools can map
from the namespace to a catalogue of schemas to validate elements within those
namespaces.
I suspect the noNamespaceSchemaLocation attributes are there because people
were used to SGML and SGML-like documents (including HTML) having a DOCTYPE
that refers to a location for a DTD. With experience, that has turned out to be
a mistake - note in HTML5 you just say "it's HTML", no mention of a DTD.
So if you're doing anything to improve XML files, I suggest you include a
namespace instead of schemaLocation and noNamespaceSchemaLocation. XML
validators and IDEs like IntelliJ IDEA and Eclipse can find the right schema
based on the namespace.
