Failed to build IHO Feature Catalogue classes from XSDs

[mikan66]

Trying to test a richer set of XSDs (attached with sample), the application issued the below runtime exception with the following command line:
.\SchematicPP.exe -v -n S100FC -o S100FCParser -i s100FC.xsd s100CSL.xsd s100CI.xsd s100CD.xsd S100Base.xsd xml.xsd xlink.xsd

Target namespace: http://www.iho.int/s100/csl/5.0
new simpleType: maxOccurs
new simpleType: UnlimitedInteger
new simpleType: S100_IntervalType
new complexType: S100_NumericRange

Caught exception: Unknown complexType child of type annotation

@mikan66 Thank you for reporting this issue!

The annotation issue is fixed cb4a874 assuming that <xs:annotation> can be ignored in the output.

However, your xsd-files appear to contain definitions that are currently not supported. Running

schematic++  -v -n S100FC -o S100FCParser -i S100FC.xsd S100CSL.xsd S100CI.xsd S100CD.xsd S100Base.xsd xml.xsd xlink.xsd

fails with

new complexType: S100_RoleCode_PropertyType
Caught exception: <attribute> missing expected attribute 'type'

where S100CI.xsd contains <xs:attribute ref="nilReason" use="optional"/> that is missing type and name attributes

  <xs:complexType name="S100_RoleCode_PropertyType">
  <xs:annotation><xs:documentation>The rolecode property is for use when roles must be allowed to be nilled.</xs:documentation></xs:annotation>
    <xs:simpleContent>
      <xs:extension base="RoleCode">
        <xs:attribute ref="nilReason" use="optional"/>
      </xs:extension>
    </xs:simpleContent>
  </xs:complexType>

The relevant code is:

schematicpp/src/main.cpp

Lines 332 to 366 in cb4a874

	else if (name == "attribute") {
	if (!child->hasAttribute(XercesString("type"))) {
	throw runtime_error("<attribute> missing expected attribute 'type'");
	}
	if (!child->hasAttribute(XercesString("name"))) {
	throw runtime_error("<attribute> missing expected attribute 'name'");
	}
	string attributeName = XercesString(child->getAttribute(XercesString("name")));
	FullName type = toFullName(XercesString(child->getAttribute(XercesString("type"))));
	bool optional = true;
	//check for optional use
	if (child->hasAttribute(XercesString("use")) && XercesString(child->getAttribute(XercesString("use"))) == "required") {
	optional = false;
	}
	std::string defaultStr;
	//check for default value
	if (child->hasAttribute(XercesString("default"))) {
	defaultStr = XercesString(child->getAttribute(XercesString("default")));
	}
	Class::Member info;
	info.name = attributeName;
	info.type = type;
	info.defaultStr = defaultStr;
	info.isAttribute = true;
	info.minOccurs = optional ? 0 : 1;
	info.maxOccurs = 1;
	cl->addMember(info);
	}

@mikan66 Sorry, I won't have time to make schematic++ support all kinds of XSD. I'd be happy to accept contributions.
