html5 - How many id's can contain the itemref? -


if onto working example of itemref usage:

<table>  <col itemscope itemref="a0 a1 a2"></col>  <tr>   <th>who</th>    <td id=a0 itemprop=band>tub ring</td>  </tr>  <tr>   <th>when</th>    <td id=a1><time itemprop=date datetime=2010-01-01>the big fool day!</time></td>  </tr>  <tr>   <th>where</th>    <td id=a2 itemprop=location>atlantis!</td>  </tr> </table>

, see, itemref can contain id's, divided space. question is: how many? how many id's can put itemref?

i have page 4 types , ca. 80 properties.

  • the easiest way not brake brain nesting of them all, write properties 1 aftter 1 down giving them id, , take type , put id's, must belong itemref.
  • the "right" way make nesting, possible, on other places use itemref.

would give me advice?

thanks

put many like. standard sets no restriction , implementation specific limit of number of properties unlikely lower itemrefs properties established via descendent elements.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
