RTIXMLParser_validateOnStartTag:Parse error at line 62: Unexpected tag 'types'

Hi, I am working on the Web Integration Service Hello World Example located here: https://community.rti.com/static/documentation/connext-dds/5.2.3/doc/manuals/web_integration_service/tutorials.html on Windows 10

I'm getting the error: RTIXMLParser_validateOnStartTag:Parse error at line 62: Unexpected tag 'types'

                                RTIXMLParser_parseFromFile_ex:Parse error in file 'C:\Program Files\rti_connext_dds-6.0.0\resource\xml\RTI_WEB_INTEGRATION_SERVICE.xml'

when I run: "%NDDSHOME%/bin/rtiwebintegrationservice" -cfgName EmptyConfiguration

I went ahead and checked out the file referenced by the error(RTI_WEB_INTEGRATION_SERVICE.xml) and sure enough it has a tag called 'types'. Here's the file:

The environment variable NDDSHOME has the value: C:\Program Files\rti_connext_dds-6.0.0

I was able to recreate the DDS tutorial in Java just fine which leads me to believe that my NDDSHOME variable is set correctly. 

Any ideas what might cause the error?
