<extended-by> Extended-by Model
Identification of an STS extension that the document claims to be following.
Usage/Remarks
The <extended-by> element names an STS extension or superset that the document claims to be following.
The content of <extended-by> may be a name or a URI of an extension. The element is repeatable so that more than
one extension can be claimed.
Processing Metadata
The Processing Metadata element (<processing-meta>) provides a more complete in-the-XML description of the tag set associated with a
document than the @dtd-version. A <processing-meta> names (through attributes) the tag set family, base tag set, table model, terminology
model, and math options a document follows and (through elements) some of the modeling
restrictions or extensions the document claims to follow.
Processing Metadata is not considered to be part of the content of a standard or adoption,
or part of the metadata for citing a standard; it is metadata about how the XML is
constructed — not about how the standard is structured. This metadata is information
at the “file level” and thus not part of <std-doc-meta> or <std-meta>, but inside the standard as a peer to <front>, which is the standard metadata container in STS.
- The Processing Metadata container element (<processing-meta>) was added to the model of <standard>, as a child element, the peer of <front> and to the model of <adoption>, as a child element, the peer of <adoption-front>.
- The elements inside <processing-meta> name tag set extensions (superset) and restrictions (subset, secondary schema, etc.) that the XML document claims to follow. More than one restriction or extension is allowed. The restrictions on an <adoption> need not be the same as on the enclosed <standard>, although they typically will be.
- The attributes on <processing-meta> describe the modeling choices made by this document in terms of tag set family, base tag set, table model, terminology model, and math tagging.
<processing-meta>
This optional container element holds the processing metadata elements that describe
processing information descriptive of the XML-tagged document (document instance).
The <processing-meta> element contains the following elements:
- <restricted-by> — Identification of one of the guidelines or other restrictions (such as a tighter subset schema) the document claims to be following. The content of <restricted-by> may be a name such as “sts4i” or a URI, for example, the URL of a particular ISO recommendation. The element is repeatable so that multiple restrictions can be claimed.
- <extended-by> — Identification of an STS extension or superset that the document claims to be following. The content of <extended-by> may be a name or a URI. The element is repeatable so that more than one extension can be claimed.
- <custom-meta-group> — To hold other processing metadata an STS user might want to express in the XML file.
