Attributes


CONVENTION

Convention for reserved names. This will normally be the name of a glossary or of a standard. It is expected that all chemical/x-* can be identied through this attribute. If omitted its value is "" which is interpreted as "LOCAL" (i.e. no communal semantics are imposed, though collaborating partners may use this if appropriate.) It is likely that a standard list of conventions will become available.

In certain contexts the CONVENTION defaults to a TecML-specific value. Thus DICTNAME within TERMENTRY refers to ISO12620 by default, and within the UNITS glossary to that glossary. In general, however, authors cannot assume any default other than the reserved values "" or LOCAL.

Value(s)

CDATA

Default Value

#IMPLIED

DICTNAME

Reserved name (in a dictionary or glossary). XVAR, ARRAY and XLIST are made specific through the use of DICTNAME, which should be in a dictionary or glossary. These may be 'official' (e.g. from a standards body, learned society, etc.) and some may be specifically mentioned in CML (e.g. every chemical/x-* type should have its own glossary). The glossary/dictionary should be identified through the CONVENTION attribute.

Processing applications are under no obligation to process DICTNAME, but in that case should pass it to other applications.

Value(s)

CDATA

Default Value

#IMPLIED

HREF

The HREF attribute is inherited from HTML2.0 and is used consistently throughout CML. It serves as the tail of a hyperlink, whose semantics are being developed by Murray Maloney and others of the HTML-WG as an Internet draft.

Here is some more information.

Value(s)

CDATA

Default Value

#IMPLIED

METHODS

Operations on destination (advisory) (HTML 2.0) (I don't understand or use this)

Value(s)

NAMES

Default Value

#IMPLIED

NAME

NAME specifies the target of a hyperlink and must be unique within a document. It is used in the same way as in HTML, but note that whereas the A element appears to refer to a point in a document, all CML elements are containers and their extent is clearly defined. Here is some more information.

Value(s)

CDATA

Default Value

#IMPLIED

REL

The REL attribute is inherited from HTML2.0 and is used consistently throughout CML. It describes the target of a hyperlink, whose semantics are being developed by Murray Maloney and others of the HTML-WG as an Internet draft.

The use of REL is under review (Jan 1997). At present it has not been used as the CML addressing mechanisms are more advanced.

Value(s)

NAMES

Default Value

#IMPLIED

REV

The REV attribute is inherited from HTML2.0 and is used consistently throughout CML. It describes the backwards relationship of a hyperlink, whose semantics are being developed by Murray Maloney and others of the HTML-WG as an Internet draft.

At present CML does not specify a use and it should evolve in parallel with what the WWW community decides.

Value(s)

NAMES

Default Value

#IMPLIED

TITLE

The TITLE attribute is inherited from HTML2.0 and is used consistently throughout CML. In HTML 2.0 it is advisory only, but you are encouraged to use it in CML since it is used to label many of the displays, tables, etc. Virtually all CML elements have this attribute.

The attribute value of TITLE is searchable, but may be better as contents of an XVAR in some cases.

Value(s)

CDATA

Default Value

#IMPLIED

URN

Permanent address of destination (HTML 2.0) (I don't use this)

CDATA
