RE: Re: [office] <style:default-style>, <style:default-page-layout>

["Dennis E. Hamilton" <dennis.hamilton@acm.org>]

I'm having trouble getting my head around this sudden willingness to have
implementation-dependent default styles and figuring out if that leaves any
prospect of broad interoperability at all.

I despair at figuring this out from the specification, so maybe it is a
matter of implementation practice.

Here are my questions, in the hope that there is an easy well-known answer
to those who are steeped in this aspect of the specification:

1. Once a document is created, are all styles that the document depends on
made explicit in the generated document or do default dependencies remain? 

2. If default dependencies remain, if the document is consumed by an
implementation that has different defaults, isn't there a risk of unintended
consequences and discrepancy between what the creator had in mind and what
the consumer sees?  (If the originally-generated document was digitally
signed, this gets even more exciting.)

3. Is the answer to (1) determined by the specification or is that itself
implementation-determined?

I agree to Rob's and Michael's opinion.

Best regards, Oliver.


P.S.: We have proposal "Add default values" - 
http://wiki.oasis-open.org/office/Add_default_values - in progress in 
order to define at least a part of default values for certain attributes
