| 180 | Namespace URIs are ignored. Namespace prefixes are included in the JSON name. | ||
| 181 | <p/> | ||
| 182 | Attributes are ignored, except for the special attribute @array="true" that | ||
| 183 | indicates the JSON serialization should write the node, even if single, as an | ||
| 184 | array, and the attribute @type that can be set to "boolean" or "number" to | ||
| 185 | dictate the value should be written as that type (unquoted). There's also | ||
| 186 | an @quote attribute that when set to true writes the inner content as text | ||
| 187 | rather than as structured JSON, useful for sending some XHTML over the | ||
| 188 | wire. | ||
| 189 | <p/> | ||
| 190 | Text nodes within mixed content are ignored. | ||
