i have experience on xml, less on namespace though i've done homework , read quite bit on namespaces on w3 site , xml validation, without finding wrong.

i appreciate help, build free online tool bit.ly/isqd4a

i've used online tools validate, , shema-check apache xml security software

tia

i use ide eclipse, intellij or xmlspy debug xsd , xml. kernow

if validate xml in such tool errors such

line 7, col 18 prefix "xs" element "xs:reelnumber" not bound.

that particular error means cant find reelnumber within xs namespace, should using dcst namespace.... , forth

targetnamespace in xsd "http://www.smpte-ra.org/schemas/428-7/2010/dcst"

the xml instance points dcst="http://www.smpte-ra.org/schemas/428-7/2007/dcst
