attribute
Qualifiers in a start-tag obeying the syntax: attributeName="attributeValue" (the quotes are highly advisable in SGML in case the attribute value contains non-SGML characters). A tag may have several independent attributes, which must have been defined in an ATTLIST statement in the DTD. Attributes may be #REQUIRED by the DTD, or they may have #IMPLIED (default) values (also given in the ATTLIST statement). The order of attributes in a tag in the document instance is irrelevant.
