[ISO/IEC 29500-1 1st Edition]

17.5.2.25 placeholder (Structured Document Tag Placeholder Text)

This element specifies the placeholder text which should be displayed when this structured document tag's run contents are empty, the associated mapped XML element is empty as specified via the dataBinding element (§17.5.2.6) or the showingPlcHdr element (§17.5.2.39) is set in the structured document tag's properties. The placeholder text which shall be shown is itself specified via the child element docPart.

If this element is omitted, then five non-breaking spaces shall be used as the default placeholder text for this structured document tag.

[Example: Consider a structured document tag defined as follows:

<w:sdt>
<w:sdtPr>
<w:placeholder>
<w:docPart w:val="DefaultPlaceholder_22610170" />
</w:placeholder>
…
</w:sdtPr>
<w:sdtContent>
…
</w:sdtContent>
</w:sdt>

This structured document tag specifies through the placeholder element that its placeholder text must be specified in the document part of type bbPlcHdr whose name is equal to DefaultPlaceholder_22610170. end example]
