XSD 1.1 failing test cases

- xs-double xs-double-004 works fine but it fails because it has a dependency on xsd 1.0 only and not on xsd 1.1.
    $zorba -q 'exists(xs:double("+INF"))'
      <?xml version="1.0" encoding="UTF-8"?>
      true

The following cases in prod-SchemaImport: substitution-020 to 025 fail because they all make use of substitution11.xsd which uses a new feature in xsd11 that current Xerces doesn't implement it.

The schema contains:
  <xs:element name="A" abstract="true" substitutionGroup="s:H1 s:H2" nillable="true"/>

In xsd10 the attribute substitutionGroup is defined as QName, while in xsd11 is defined as List of QName. Since Xerces expects a QName and value "s:H1 s:H2" is not, hence the error.

Tests fn-adjust-dateTime-to-timezone/cbcl-adjust-dateTime-to-timezone-001 and 004 pass correctly.

Tests prod-CastExpr/K2-SeqExprCast-231 and K2-SeqExprCast-232 already have a W3C bug assigned, a.k.a.
https://www.w3.org/Bugs/Public/show_bug.cgi?id=21263 See Sorin's original bug description.

Test xs-double/xs-double-004 works fine is missing xsd11 dependency. See my comment#1.

Opened lp:1170441 for the remaining failures.
