Yes yes yes. ;-)

If 'text-decoration' is applied to a SPAN element which contains,
amongst other things, some text, then all the contents of the SPAN
should be underlined, since the underlining spans all descendants.


   <span style="text-decoration: underline">
      <em>some text</em>
      <img src="..." alt="an image">
      <em>some text</em>

...would result in:

   some text [X] some text

...and not:

   some text [X] some text
   ----------   ----------

Note that the EM and IMG elements do not have 'text-decoration' set.
The underlining does not apply to the IMG element at all, since it is
not _set_ on the IMG element. According to CSS2:

# If the property is specified for a block-level element, it affects
# all inline-level descendants of the element. If it is specified for
# (or affects) an inline-level element, it affects all boxes generated
# by the element.

Thus every box inside an element which has 'text-decoration' set to
'underline', regardless of whether it is an inline level or a block
level element, will be affected. Including IMG elements, which
generate boxes just like any other element.
