Example AutoTask Appointment

appointment_spec.rb

require 'spec_helper'

describe AutotaskAPI::Appointment do
  xml = '
            <id>76</id>
            <UserDefinedFields/>
            <ResourceID xsi:type="xsd:int">29684244</ResourceID>
            <Title xsi:type="xsd:string">Example Appointment</Title>
            <StartDateTime xsi:type="xsd:dateTime">2015-02-07T05:21:00</StartDateTime>
            <EndDateTime xsi:type="xsd:dateTime">2015-02-07T05:22:00</EndDateTime>
            <Description xsi:type="xsd:string">Example of a really cool description</Description>
            <CreatorResourceID xsi:type="xsd:int">296068</CreatorResourceID>
            <CreateDateTime xsi:type="xsd:dateTime">2015-02-07T12:21:56.53</CreateDateTime>
            <UpdateDateTime xsi:type="xsd:dateTime">2015-02-07T12:21:56.547</UpdateDateTime>
'
  subject(:appointment) {AutotaskAPI::Appointment.new(xml)}

	it 'create valid appointment' do
		expect(subject.title).to eq('Example Appointment')
	end
end

title is empty when I pass in this example.
