The @when attribute cannot be used with any other att.datable.w3c attributes. The @from and @notBefore attributes cannot be used together. The @to and @notAfter attributes cannot be used together. @calendar indicates the system or calendar to which the date represented by the content of this element belongs, but this element has no textual content. The @xml:id "" on ＜＞ duplicates an @xml:id found earlier in the document The @unit attribute may be unnecessary when @unitRef is present. The element should not be categorized in detail with @subtype unless also categorized in general with @type @targetLang should only be used on if @target is specified. @schemeVersion can only be used if @scheme is specified. Abstract model violation: Paragraphs may not occur inside other paragraphs or ab elements. Abstract model violation: Lines may not contain higher-level structural elements such as div, p, or ab. Information about a deprecation should only be present in a specification element that is being deprecated: that is, only an element that has a @validUntil attribute should have a child <desc type="deprecationInfo">. Only one of the attributes @target and @cRef may be supplied on . Only one of the attributes @target' and @cRef' may be supplied on The content of a "gloss" list should include a sequence of one or more pairs of a label element followed by an item element If the @target attribute on is used, the relatedItem element must be empty A relatedItem element should have either a 'target' attribute or a child element to indicate the related bibliographic item Abstract model violation: Lines may not contain higher-level structural elements such as div. Abstract model violation: p and ab may not contain higher-level structural elements such as div. @maxOccurs should be greater than or equal to @minOccurs When @maxOccurs is not specified, @minOccurs must be 0 or 1 Specification : the value of the module attribute ("") should correspond to an existing module, via a moduleSpec or moduleRef A deprecated construct should include, whenever possible, an explanation, but this does not have a child <desc type="deprecationInfo"> a ＜moduleRef＞ that uses the url= attribute should have a prefix= attribute, too The '' module is included (by reference)
