recordIdentifier isn't included into sruResponse.xsd

Dear colleagues,

I've just discovered an inconsistency between SRU2.0 (and 1.2 too) 
specification at http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/os/part3-sru2.0/searchRetrieve-v1.0-os-part3-sru2.0.html#_Toc234915120 and corresponding schema at http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/os/schemas/sruResponse.xsd - it seems 
that schema doesn't contain definition of recordIdentifier element.

Sincerely,
Rustam
