If you create document then app.xml is "default"
Ex:
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
- <Properties xmlns="http://schemas.openxmlformats.org/officeDocument/2006/extended-properties" xmlns:vt="http://schemas.openxmlformats.org/officeDocument/2006/docPropsVTypes">
<Template>Normal.dotm</Template>
<TotalTime>0</TotalTime>
<Pages>1</Pages>
<Words>1</Words>
<Characters>1</Characters>
<Application>Microsoft Office Word</Application>
<DocSecurity>4</DocSecurity>
<Lines>1</Lines>
<Paragraphs>1</Paragraphs>
<ScaleCrop>false</ScaleCrop>
<Company>Company</Company>
<LinksUpToDate>false</LinksUpToDate>
<CharactersWithSpaces>1</CharactersWithSpaces>
<SharedDoc>false</SharedDoc>
<HyperlinksChanged>false</HyperlinksChanged>
<AppVersion>12.0000</AppVersion>
</Properties>
But it is not true! you may have more than 1 page, 1 Word, etc
Thanks
