| doc | (document or file) specifies the document within which the desired location is to be
found. |
| Datatype: ENTITY |
| Values: The name of a system entity associated with the document within
which the target of this extended pointer is to be found, by default the
current document. |
| Default: #IMPLIED |
| Example:
<xptr doc='Chap2' from='id (e23)'>
|
| Note | The system entity named by this attribute must be declared
(as a SUBDOC entity or a non-SGML entity)
in the DTD of the document containing the extended pointer.
|
| from | specifies the start of the destination of the pointer, as an
expression in the TEI extended-pointer notation described in section
14.2 . |
| Datatype: %extPtr; |
| Values: The value specified must be a valid expression in the TEI
extended pointer notation defined in section 14.2 . |
| Default: "ROOT" |
| Example:
|
| Note | If no value is specified, the target is the whole of the
document identified by the doc attribute.
|
| to | specifies the endpoint of the destination of the pointer, as an
expression in the TEI extended pointer notation. |
| Datatype: %extPtr; |
| Values: The value specified must be a valid expression in the TEI
extended pointer notation defined in section 14.2 . |
| Default: "DITTO" |
| Example:
<xptr doc=OrbisPictus from='id (animalia)'
to='id (aquaticae)'>
|
| Note | This attribute may only be supplied if the from
attribute is also supplied, in which case the destination is defined to
extend from the beginning of the location specified by the
from attribute, up to the end of that specified by the
to attribute. It is an error for the to
attribute to specify a location whose end precedes the beginning of the
location specified by from ; it is not an error for the scopes
to overlap.
If no value is specified, the target is the location specified by the
from attribute.
