Exclude unwanted "xml" tags from schema.

We managed to solve this ourselves. We're processing the OpenApi object once it's finished generating, through this object we have access to schemas and their corresponding objects

private OpenAPI getOpenAPISpecification(final OpenApiContext openApiContext, final boolean isTenantIndependent) {
    final OpenAPI openApiSpecification = getOpenApiSpecification();

    // This will remove any tags from schema components and their children related to XML.
    openApiSpecification.getComponents().getSchemas().forEach((k, schema) -> {
        if (schema.getXml() != null) {
            schema.setXml(null);
        }
        final Map<String, Schema> childSchemas = schema.getProperties();
        if (childSchemas != null) {
            removeXmlTagsFromSchemas(childSchemas.values());
        }
    });
    return openApiSpecification;
}

private static void removeXmlTagsFromSchemas(final Collection<Schema> schemas) {
    schemas.forEach(schema -> {
        if (schema == null) {
            return;
        }
        if (schema.getXml() != null) {
            schema.setXml(null);
        }
        final Schema<?> item = schema.getItems();
        if (item != null && item.getXml() != null) {
            item.setXml(null);
        }
        final Map<String, Schema> childSchemas = schema.getProperties();
        if (childSchemas != null && !childSchemas.isEmpty()) {
            // Recursive call to remove tags from deeply nested schemas
            removeXmlTagsFromSchemas(childSchemas.values());
        }
    });
