refunit |
(reference unit)
names the unit (book, chapter, canto, verse, ...) identified
by this step in a canonical reference. |
|
Datatype: CDATA |
|
Values: any string of characters; typically a word or phrase in
some natural language. |
|
Default: #IMPLIED |
Note |
The provision of this attribute helps make the structure
of the canonical reference much clearer.
Its use is strongly recommended.
|
length |
specifies the fixed length of the reference component. |
|
Datatype: CDATA |
|
Values: Should be a positive integer; if no value is provided,
the length is unlimited and goes to the next delimiter or to the
end of the value. |
|
Default: #IMPLIED |
Note |
When constructing a reference, if the reference component
found is of numeric type, the length
is made up by inserting leading zeros; if it is not, by inserting
trailing blanks. In either case, reference components are truncated
if necessary at the right hand side.
When seeking a reference, the length indicates the
number of characters which should be compared. Values longer than
this will be regarded as matching, if they start correctly.
|
delim |
supplies a delimiting string following the reference
component. |
|
Datatype: CDATA |
|
Values: If a single space is used it is interpreted as
whitespace |
|
Default: #IMPLIED |
from |
specifies the starting point of the area referred to by this
step in the canonical reference. |
|
Datatype: %extPtr; |
|
Values: a valid expression in the TEI extended pointer notation
documented in section 14.2 Extended Pointers. |
|
Default: #REQUIRED |
to |
specifies the ending point of the area referred to by this step
in the canonical reference. |
|
Datatype: %extPtr; |
|
Values: a valid expression in the TEI extended pointer notation
documented in section 14.2 Extended Pointers. |

Default: DITTO |
