A text input form. No one actually uses this. Why are you?
The title of the text input form, which would go in the value attribute of the form's submit button.
The link of the script which processes the text input form, which would go in the action attirbute of the form.
If this is a relative URI, it is resolved according to a set of rules.
The name of the text input box in the form, which would go in the name attribute of the form's input box.
A short description of the text input form, which would go in the label element of the form.
This is a text input in a feed:
<textInput> <title>Go!</title> <link>http://example.org/search</link> <name>keyword</name> <description>Search this site:</description> </textInput>
This is how it could be rendered in HTML:
<form method="get" action="http://example.org/search"> <label for="keyword">Search this site:</label> <input type="text" id="keyword" name="keyword" value=""> <input type="submit" value="Go!"> </form>
