8 Common Attributes:
9
10 id The id attribute allows authors to name elements such as
11 headers and paragraphs as potential destinations for links.
12 Note links don't specify points, but rather extended objects.
13
14 index Allows authors to specify how given headers etc should be
15 indexed as primary or secondary keys, where "/" separates
16 primary from secondary keys ";" separates multiple entries

239
240 These elements define fields which users can type into or select with mouse
241 clicks. The browser should manage the input focus e.g. with the tab/shift
242 tab keys and mouse clicks.
243
244 The enter/return key is then taken to mean the use has filled in the form
245 and wants the apppropriate action taken:
246
247 - send as query/update to WWW server
248 - email/fax to designated person
249
250 The action is specified as a URL, e.g. "mailto:dsr@hplb.hpl.hp.com You can
251 specify additional mail headers with the MH tag:
252
253 <MH>Subject: Please add me to tennis tournament</MH>
254

272 Users can alter the value of the INPUT element by typing or clicking with
273 the mouse. Use radio buttons for selecting one attribute value from a set
274 of alternatives. In this case there will be several INPUT elements with the
275 same name. Attributes which can take multiple values at the same time
276 should be defined with checkboxes: define each allowed value in a separate
277 INPUT element but with the same attribute name. For checkboxes and radio
278 buttons, the value doesn't change, instead the state of the button shown by
279 the presence or absence of the checked attribute in each element.
280 The size attribute specifies the size of the input field as appropriate to
281 each type. For text this gives the width in characters and height in lines
282 (separated by an "x"). For numbers this gives the maximum precision.

364 automatically by the browser.

366 FIGT can also be used to position a graphic on top of a picture using an
367 IMG element within FIGT. In this case the chromakey attribute may allow
368 parts of the underlying image to show through.
