R&S surName vs sn

[Tompkins,Charles R]

Hi All,

I am researching R&S for IdP and need a little clarification.

Referencing this document: Configure a Shibboleth IdP to Support R and S 
(https://spaces.internet2.edu/display/InCCollaborate/Configure+a+Shibboleth+IdP+to+Support+R+and+S), 
I see the example titled "Configure a New AttributeFilterPolicy".  It 
has the following line:

<AttributeRule attributeID="surName">

However, when I check the "InCommon Federation Attribute Summary" 
(http://www.incommon.org/federation/attributesummary.html), I see the 
attribute "sn" defined, but not "surName".

Is this just a documentation typo or will I need to present "surName" in 
the assertion to R&S SP's?

TIA,
-Charles
