<h2>Introduction</h2> |
| 82 |
|
| 83 |
<p>Recently, a number of auto-discovery conventions |
| 84 |
are proposed and implemented in various Web browsers |
| 85 |
and so-called <q>Web 2.0</q> services. They provide |
| 86 |
means to extract links to resources (or other useful |
| 87 |
information) from Web documents in somewhat reliable |
| 88 |
ways. However, the syntax of these techniques |
| 89 |
vary and the implementators have to add specific |
| 90 |
code for each auto-discovery technique.</p> |
| 91 |
|
| 92 |
<p>The <dfn id="DT-autodiscovery-autodiscovery">Auto-Discovery |
| 93 |
Auto-Discovery</dfn> is a mechanism to discover |
| 94 |
auto-discovery element that contains links (or |
| 95 |
other information) for auto-discovery techniques. |
| 96 |
With the Auto-Discovery Auto-Discovery, user agents |
| 97 |
can detect auto-discovery elements without any |
| 98 |
particular knowledge to a specific auto-discovery |
| 99 |
technique.</p> |

For example, a <a href="#DT-referencing-element">referencing element</a> |

For example, no elements in the HTML namespace other than |

<p>Note also that <a href="#DT-referencing-element">referencing element</a>s |
