attribute extraction template file A text file that determines which attributes are extracted
and how they are formatted when written to an attribute extraction file. See also attribute
extraction file.
attribute prompt The text string displayed when you insert a block with an attribute whose
value is undefined. See also attribute definition, attribute tag, and attribute value.
attribute tag A text string associated with an attribute that identifies a particular attribute
during extraction from the drawing database. See also attribute definition, attribute prompt,
