Element 'assert' is invalid, misplaced, or occurs too often

问题

We were provided a set of schemas from a vendor, (we have alerted them to the error as well).
When I try to generate the Java classes using xjc, it fails with the error below

C:\Users\...>"C:\Program Files (x86)\Java\jdk1.7.0_80\bin\xjc.exe" -d output ICSv1.01.xsd

parsing a schema...

[ERROR] s4s-elt-invalid-content.1: The content of 'ICSBatchV01' is invalid. Element 'assert' is invalid, misplaced, or occurs too often. line 77 of file:/C:/Users/.../ICSv1.01.xsd

[ERROR] s4s-elt-invalid-content.1: The content of 'ICSDocBody' is invalid. Element 'assert' is invalid, misplaced, or occurs too often. line 215 of file:/C:/Users/.../ICSv1.01.xsd

Failed to parse a schema.

I also tried java 8, and the latest and greatest jaxb (outside of java dist)

However, it does work with Altova's xmlspy software, but trying to avoid vendor lock-in/non standard stuff.
I did some searching here and the web (mostly here)

Here is the header.

XSD 1.1 is required for xs:assert, but JAXB only supports XSD 1.0, not XSD 1.1. None of the requests to add support for XSD 1.1 have be addressed (references: here and here).

What to do:

Contribute support yourself, or hope that someone else does (unlikely).
In the meantime, analyse the XSDs for 1.1 dependencies. If mild, such as only use of xs:assert, write a simple XSLT transformation to strip xs:assert validations so that you can still generate classes. (See XSLT below.) Optionally, as needed, implement the xs:assert checks in Java code manually.

XSLT to strip xs:assert:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xsl:template match="@*|node()">
    <xsl:copy>
      <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="xs:assert"/>
</xsl:stylesheet>
