why can't I validate this xml against this xsd?

Question

I can't seem to validate http://pastebin.com/jbFzRuUD against http://pastebin.com/cgvTdVWA

Here are the errors I get:

  /schema-check xml.xml xsd.xsd 
    Error at file "/stuff/xml.xml", line 3, column 63
     Message: Unknown element 'dcst:SubtitleReel'

I have some experience on xml, less on namespace though I've done my homework and read quite a bit on namespaces on w3 site and xml validation, without finding what was wrong.

I would appreciate any help, this is to build a free online tool bit.ly/isqd4a

I've used online tools to validate, and also shema-check from Apache xml security software

I usually use a IDE like eclipse, intellij or XMLSpy to debug XSD and XML. Kernow is also good

If you validate the XML in such a tool you get errors such as

Line 7, Col 18 The prefix "xs" for element "xs:ReelNumber" is not bound.

That particular error means that it cant find ReelNumber within the xs namespace, you should be using the dcst namespace.... and so forth

targetNamespace in XSD is "http://www.smpte-ra.org/schemas/428-7/2010/DCST"

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