| 850 | // we are still deliberately keeping attribute *names* restricted. |
| 851 | // This is a deliberate design choice. Dynamically-generated |

| 853 | // fragment datatype, which is one of the fragment types from which |
| 854 | // the output document can be composed -- but that composition |
| 855 | // mechanism and the way the fragment composition is reflected in |
| 856 | // the DOM is out-of-scope for this API. This just provides a |
| 857 | // richer way to embed complex information of that sort into a |
| 858 | // DOM document. |
| 859 | |
| 860 | // An important design decision here was not to embed type information |
| 861 | // for attributes into the representation, which is done to avoid |
| 862 | // HTML bloat. This leads directly to a "lazy load" implementation, |
| 863 | // as we can't actually load an attribute value until we know what |
| 864 | // its class type is, and that's only provided when the call to |
| 865 | // ::getAttributeObject() is made. In order to implement an "eager |
| 866 | // load" implementation, we would need a schema for the document |
| 867 | // which maps every named attribute to an appropriate type. This |
| 868 | // is possible if eager loading is desired in the future, or because |
| 869 | // you like the added structural documentation provided by a schema. |
| 870 | |
| 871 | // Certain attributes have semantics given by HTML. For example, |
| 872 | // the `class` and `alt` attributes shouldn't be serialized as a |
| 873 | // JSON blob, even if you want to store a rich value. For these |
| 874 | // "HTML attributes with special semantics" (everything not |
| 875 | // starting with data-* at the moment) we tolerate a bit of bloat |
| 876 | // and store a flattened string representation of the rich value |
| 877 | // in the direct HTML attribute, and store the serialized rich |
| 878 | // value elsewhere. This value is used to provide the appropriate |
| 879 | // HTML semantics (ie, the browser will apply CSS styling to the |
| 880 | // flattened `class`, use the flattened `href` to navigate) but |
| 881 | // should not be used by clients /of the MediaWiki DOM spec/ |
| 882 | // (including Parsoid), which should ignore the flattened value |
| 883 | // and consistently use the rich value in order to avoid |
| 884 | // losing/overwriting data. |
| 885 | |
| 886 | // The JSON representation of a rich valued attribute can be |
| 887 | // customized using the mechanisms provided by the wikimedia/json-codec |
| 888 | // library; in particular you will want to use the "implicit typing" |
| 889 | // mechanism provided by the library to avoid bloating the output |
| 890 | // with explicit references to the PHP implementation classes. |
| 891 | |
| 892 | // See |
| 893 | // https://www.mediawiki.org/wiki/Parsoid/MediaWiki_DOM_spec/Rich_Attributes |
