<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 |
</div> |
means to extract links to resources (or other useful |
87 |
|
information) from Web documents in somewhat reliable |
88 |
<div class="section"> |
ways. However, the syntax of these techniques |
89 |
