Notes
In LSExtendedSearchCommand this is bound to the 'content' of EOSQLQualifier
and contains an array like:
"(", "(", "(", LOWER, "(", { allowsNull=Y; columnName=name; width=50;...},
...
" = ", 0, ")", ")"
so it seems to be a stream of tokens and an EOAttribute mixed in for column
keys.
Apparently only EOSQLExpression supports the 'EOExpressionContext'?
