tag	The unique identifier (name) for a tag in a specific taxonomy release.
version	For a standard tag, an identifier for the taxonomy; otherwise the accession number where the tag was defined.
custom	1 if tag is custom (version=adsh), 0 if it is standard. Note: This flag is technically redundant with the version and adsh columns.
abstract	1 if the tag is not used to represent a numeric fact.
datatype	If abstract=1, then NULL, otherwise the data type (e.g., monetary) for the tag.
iord	If abstract=1, then NULL; otherwise, “I” if the value is a point-in time, or “D” if the value is a duration.
crdr	If datatype = monetary, then the tag’s natural accounting balance (debit or credit); if not defined, then NULL.
tlabel	If a standard tag, then the label text provided by the taxonomy, otherwise the text provided by the filer. A tag which had neither would have a NULL value here.
doc	The detailed definition for the tag. If a standard tag, then the text provided by the taxonomy, otherwise the text assigned by the filer. Some tags have neither, and this field is NULL.
