Subject: [OASIS Issue Tracker] Commented: (OFFICE-2318) Public Comment: EBNF(ODF all versions) (CLONE)

    [ http://tools.oasis-open.org/issues/browse/OFFICE-2318?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=18849#action_18849 ] 

Dennis Hamilton commented on OFFICE-2318:


In draw:formula and anim:formula, it would be valuable to have used the [XML 1.0] S and S? where wsp and wsp* are now defined and used.

In draw:formula, there is something wrong with the produciton for name.

In draw:formula and anim:formula, it is probably better to use unary_expression, not unnary_expression.  (It has an optional unary operator is all.)

Also, the grammar could just as easily be

unary_expression ::= ('-' wsp*)? basic_expression

Note that there is an odd case when the basic_expression is a signed number.  Some languages handle that by having the prefix sign be in the unary_expression and not in the syntax for number itself.  That is,

  unary_expression ::= (sign wsp*)? basic_expresson

and sign? is pulled out of the production for number.

What is meant by a function_reference here?  It looks like we should use formula_name here, to match up with the description in the text.

Are modifiers indexed starting with 0 or 1?  The syntax allows 0.
