Patrick Durusau updated OFFICE-3953:
------------------------------------
Proposal:
Change schema to
{code:xml}
<attribute name="style:first-page-number">
<choice>
<ref name="Integer"/>
<value>continue</value>
</choice>
</attribute>{code}
Â
was:
Change schema to
{code:xml}
<attribute name="style:first-page-number">
<choice>
<ref name="Integer"/>
<value>continue</value>
</choice>
</attribute>{code}
and exchange {{integer}} in text with {{non negative integer}}.
> Allow presentation to start with slide number 0

> Key: OFFICE-3953
> URL: https://issues.oasis-open.org/browse/OFFICE-3953
> Project: OASIS Open Document Format for Office Applications (OpenDocument) TC
> Issue Type: New Feature
> Components: Presentation
> Affects Versions: ODF 1.2
> Reporter: Regina Henschel
> Priority: Minor
> Fix For: ODF 1.4

>
> PowerPoint allows, that a presentation starts with number 0. The start value of slide numbering is given by the attribute {{firstSlideNum}} of element {{<p:presentation>}} in OOXML. Even negative values are allowed in OOXML.
> {code:xml}<xsd:attribute name="firstSlideNum" type="xsd:int" use="optional" default="1"/>{code}
> The corresponding attribute in ODF is {{20.258 style:first-page-number}}. Here we have the description text
> {quote}The value of this attribute can be an integer or continue.{quote}
> But in the schema there is
> {code:xml}<attribute name="style:first-page-number">
> <choice>
> <ref name="positiveInteger"/>
> <value>continue</value>
> </choice>
> </attribute>{code}
>
> So my suggestion is to allow at least the value 0 too. LibreOffice has not yet implemented the attribute {{style:first-page-number}}, but there exists an enhancement request about more flexible page numbering https://bugs.documentfoundation.org/show_bug.cgi?id=115611 . I have no strong opinion, whether negative values should be allowed. For interoperability with pptx format of PowerPoint or SoftMaker, only value 0 is needed.
> We have made a similar change in https://issues.oasis-open.org/browse/OFFICE-3923 for the attribute {{style:page-number}}, which is used in text documents.
