BNF Grammar Quote issues

                 Key: CMIS-527
                 URL: http://tools.oasis-open.org/issues/browse/CMIS-527
             Project: OASIS Content Management Interoperability Services (CMIS) TC
          Issue Type: Bug
          Components: Domain Model
            Reporter: Ryan McVeigh
            Assignee: Ethan Gur-esh


CMIS defers to SQL-92 for the description of <character string literal>.  SQL-92 (http://www.contrib.andrew.cmu.edu/~shadow/sql/sql1992.txt) defines a character string literal as delimited by <quote>, which is defined as <quote> ::= ', that is, a single-quote character.

CMIS BNF defines <quote> ::= '"' | "'", that is either a single- or double-quote character.
          - Is CMIS attempting to "override" or "extend" the SQL definition of the <quote> production, or is CMIS's usage unique to where it is explicitly used in the CMIS text.
          - Specifically, does CMIS's <quote> affect the <character string literal> as defined in SQL-92?

The <text search expression> for the CONTAINS operator is specified to be delimited only by double-quote characters, not the single-quotes prescribed for SQL-92 strings, nor the "either-quotes" used within the expression itself.  The <datetime literal> is delimited with "either-quotes", unlike character string literals.  The example in section 2.10.2.4.2.3 uses double-quotes, which hints that maybe CMIS is trying to override SQL's definition of <quote>.
