I'd like to create an XML schema that will ensure a certain simple
structure exists in the document but allows for any other elements or
attributes.
I've attached an invalid XSD which is close to what I want. If I remove
the anyType complex type and it's references the XSD is then valid and
will validate my XML document correctly but there is no allowance for
any elements or attributes beyond what is defined in the XSD. I'd rather
have the XSD define a set of required elements and their structure but
allow for any other elements and attributes in the document. I hope that
description make sence and any help is very much appreciated.
Thank you,
Eric Dalquist
PS: The error Oxygen is giving me with the attached XSD is:
E cos-nonambig: WC[##any] and "":folder (or elements from their
substitution group) violate "Unique Particle Attribution". During
validation against this schema, ambiguity would be created for those two
particles. layout.xsd 24:39
