Definition in the specification
Table 220 · Entries common to all field dictionaries
ISO 32000-1:2008, §12.7.3.1 · PDF page 441 ↗
/TU text string
(Optional; PDF 1.3) An alternate field name that shall be used in place of the actual field name wherever the field shall 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 14.9.3, “Alternate Descriptions”).
Qualifier: Optional; PDF 1.3
Conditional descriptions remain traceable. A definition alone does not implement a codec, a signature or every format mechanism. Read the coverage.
