| 66 | <dd> |
| 67 | Register the <var>factory</var> function with the name <var>name</var>. The |
| 68 | factory function should return an object which implements the |
| 69 | <tt class="class">DOMImplementation</tt> interface. The factory function can return |
| 70 | the same object every time, or a new one for each call, as appropriate |
| 71 | for the specific implementation (e.g. if that implementation supports |
| 72 | some customization). |

| 84 | succeeds. If no name is given, and if the environment variable |
| 85 | <a class="envvar" id='l2h-4359' xml:id='l2h-4359'>PYTHON_DOM</a> is set, this variable is used to find the |
| 86 | implementation. |

| 90 | find one with the required feature set. If no implementation can be |

| 92 | sequence of <code>(<var>feature</var>, <var>version</var>)</code> pairs which are |

| 161 | the DOM specification; concrete DOM implementations must provide |
| 162 | those. The <tt class="class">Node</tt> class provided as part of this module does |
| 163 | provide the constants used for the <tt class="member">nodeType</tt> attribute on |
| 164 | concrete <tt class="class">Node</tt> objects; they are located within the class |
| 165 | rather than at the module level to conform with the DOM |
| 166 | specifications. |
