Ow, in iText, this can be set using the method
PdfFormField.setUserName(String s);
I looked in the PDF Reference for "tool tip" but I only found it
in the section about actions. The description for the /TU value is
"An alternate field name to be used in place of the actual field name 
wherever the field must be identified in the user interface (such as in 
error or status messages referring to the field). This text is also 
useful when extracting the document’s contents in support of 
accessibility to users with disabilities or for other purposes (see 
Section 10.8.2, "Alternate Descriptions")."
I didn't know it was used as a tool top.
