HTML Publish Location

Source Relationship:

http://schemas.openxmlformats.org/officeDocument/2006/relationships/ htmlPubSaveAs

When a presentation specifies an external location to which an optional copy might be pushed in the HTML format, this relationship shall be used to target the location where the HTML copy of the presentation is published.

A package shall contain one HTML Publish Location relationship for each slide linked with an HTML publish location, and that relationships shall be an explicit relationship from the corresponding Presentation Properties (§13.3.7) part.

example:
<Relationships xmlns="…">
  <Relationship Id="rId1" 
    Type="http://…/htmlPubSaveAs" 
    Target="http://www.openxmlformats.org/test.htm" type=”External”/>
</Relationships>

An HTML publish location shall be located external to the package containing the source relationship (expressed syntactically, the @TargetMode attribute of the <Relationship> element shall be External).
