17.16.16 helpText (Associated Help Text)
This element specifies optional help text which shall be associated with the parent form field. The method or user interface by which this help text can be surfaced is not defined by ISO/IEC 29500.
If this element is omitted, then no help text shall be associated with the current form field.
[Example: Consider the following WordprocessingML fragment for a drop-down list form field:
<w:fldSimple w:instr="FORMDROPDOWN">
<w:ffData>
<w:helpText w:type="text" w:val="Example help text." />
<w:ddList>
…
</w:ddList>
</w:ffData>
</w:fldSimple>
The helpText element specifies the help text for the parent form field - in this case, literal help text consisting of the string Example help text.end example]
