I'm having trouble with the expression validator not liking the name of my C

I'm having trouble with the expression validator not liking the name of my CDT. I have a cdt that is based off of an xml standard (MISMO if you're curious). Some of the field names start with an underscore and when I try to reference them in the expression editor I get the following error and cannot save the expression. "The character _ could not be recognized in the given context." This is the expression that I'm trying to save. "median(pv!cdtResponse_Group.RESPONSE.RESPONSE_DATA.CREDIT_RESPONSE.CREDIT_SCORE.@attributes._Value)"

Since Appian runs in java and java does not like having an underscore at the start of a variable name, is that why I'm not able to use this expression? I'm still able to view these values if I reference a higher level in the cdt, so I'm guessing there's some Appian magic going on that keeps the names acceptable. If that's the case can I disable the validator? ...

Correction, I checked and oracle only discourages the _ as the first character of a variable name. It is still "Technically Legal".

This data is being converted to and from xml, so I'd like to avoid changing the naming convention. Since the toxml and torecord functions make that so easy :-)
