Found a incorrect sample file

[lexchou]

I found a issue during making our own 3mf loaders:

File 3D/3dmodel.model in MUSTFAIL_Chapter3.4.1a_MissingMetadataName.3mf

  <metadata name="Undefined" >Microsoft Corporation</metadata>
  <metadata name="Title">Dice</metadata>
  <metadata name="Description">Dice 100</metadata>
  <metadata name="Copyright">© Microsoft Corporation 2015</metadata>
  <metadata name="LicenseTerms">All rights reserved</metadata>
  <metadata name="Rating" />
  <metadata name="CreationDate">2015-10-28</metadata>
  <metadata name="ModificationDate">2015-10-28</metadata>

According to its file name there should have a metadata element without a name attribute, but every elements here has a name attribute.

BTW: Can someone explains the MUSTFAIL_Chapter2.3.2c_UndefinedNameSpaceInXDS.3mf ? I looked a lot but I don't understand which place is incorrect.

@lexchou we are in the process of rebuilding our validation test suite, and will be re-releasing it as soon as possible with better documentation and more complete testing. Sorry for the delay!
