<h3 id="text-decoration-skip-property">
Text Decoration Line Continuity: the 'text-decoration-skip' property</h3>

This specification extends the 'text-decoration-skip' property
present in level 3
by adding the ''trailing-spaces'' value.

<pre class="propdef">
Name: text-decoration-skip
Value: ''none'' | [ ''objects'' || [ ''spaces'' | ''trailing-spaces'' ] || ''ink'' || ''edges'' || ''box-decoration'' ]
Initial: objects
Applies to: all elements
Inherited: yes
Percentages: N/A
Media: visual
Computed value: as specified
Animatable: no
</pre>

Issue: Add final level 3 content

<dl dfn-type=value dfn-for=text-decoration-skip>
<dt><dfn>none</dfn></dt>
<dt><dfn>objects</dfn></dt>
<dt><dfn>spaces</dfn></dt>
<dt><dfn>ink</dfn></dt>
<dt><dfn>edges</dfn></dt>
<dt><dfn>box-decoration</dfn>
<dd>

Issue: Add final level 3 content
<dt><dfn>trailing-spaces</dfn></dt>
<dd>Skip all spacing, i.e. all <i>characters</i> with the Unicode White_Space property [[UAX44]]
and all <a href="http://www.w3.org/TR/css3-text/#word-separator">word separators</a>,
plus any adjacent 'letter-spacing' or 'word-spacing'
when located then end of the line.
</dl>

Issue: Should ''object trailing-spaces'' be the initial value instead of just ''object''?
Should the initial value be auto,
defined so that that it can vary between
''object'' and ''object trailing-spaces''
depending on properties like 'white-space', 'word-wrap', 'word-break' etc?

Issue: Should we have a ''leading-spaces'' value as well?
It looks like ''object leading-spaces'' may be more appropriate than
''object trailing-spaces'' in right-aligned text,
even though common word processing applications don't do that.
