-  and the area to fill can be rotated or flipped depending on the text flow.

-  Name: background-image-transform
-  Value: logical | physical | rotate
-  Initial: physical
-  Applies to: all elements
-  Inherited: yes
-  Percentages: n/a

-
-  This property defines whether background images are transformed
-  to match to the value of 'writing-mode' property,
-  and whether 'background-size' widths and heights are flow-relative or physical.
-  Values have the following meanings:
-
-  <dl dfn-type="value" dfn-for="background-image-transform">
-    <dt><dfn>logical</dfn></dt>
-    <dd>
-      The values for the 'background-size' property are flow-relative.
-      The background images are transformed to match to the flow-relative axis.
-
-    <dt><dfn>physical</dfn></dt>
-    <dd>
-      The values for the 'background-size' property are physical.
-      The background images remain unchanged.
-
-    <dt><dfn>rotate</dfn></dt>
-    <dd>
-      Similar to ''background-image-transform/logical'', except that the <a>inline base direction</a> is ignored.
-      The result is affected only by the <a>block flow direction</a>.
-  </dl>
-
-<h3 id="background-repeat-prop">
-The 'background-repeat' property</h3>
-
-  The ''repeat-x'' and ''repeat-y'' values are physical,
-  but in CSS3 this property can also accept double values
-  to specify horizontal and vertical behaviors separately.
-  The double values are considered flow-relative
-  if the ''background-image-transform/logical'' keyword is specified,
-  otherwise physical.
-
-  <p class="issue">
-    should also add repeat-horizontal and repeat-vertical for the physical value?

-Border Image Transform: The 'border-image-transform' property</h3>
-
-  <pre class="propdef">
-  Name: border-image-transform
-  Value: logical | physical | rotate
-  Initial: rotate
-  Applies to: All elements, except internal table elements when 'border-collapse' is ''border-collapse/collapse''

-  <p class="issue">
-    is this the right initial default?
-
-  This property defines whether border images are transformed
-  to match to the value of 'writing-mode' property,
-  with the reference writing mode being
-  ''writing-mode: horizontal-tb; direction: ltr''.
-  Values have the following meanings:
-
-  <dl dfn-type="value" dfn-for="border-image-transform">
-    <dt><dfn>logical</dfn></dt>
-    <dd>
-      The values for the border-image-* properties are flow-relative.
-      The border images are transformed to match to the flow-relative axis.
-
-    <dt><dfn>physical</dfn></dt>
-    <dd>
-      The values for the border-image-* properties are physical.
-      The border images remain unchanged.
-
-    <dt><dfn>rotate</dfn></dt>
-    <dd>
-      Similar to ''border-image-transform/logical'',
-      except that the <a>inline base direction</a> is ignored.
-      The result is affected only by the <a>block flow direction</a>.
-  </dl>
-
-  The following properties use the value of this property
-  to determine how directional mappings are done:
-  <ul>
-    <li>'border-image-slice'
-    <li>'border-image-width'
-    <li>'border-image-outset'
-    <li>'border-image-repeat'
-    <li>'border-image'

 Changes</h2>
 
-  Changes since the earlier Editors Drafts include:
+  Changes since the previous Working Draft include:
+  <ul>
+    <li>Removing the features for logical background and border-images.
+        (These ideas may be revisited in a future draft.)
+    <li>Adding the logical 'border-radius' longhands.
+  </ul>
+
+  Changes between the earlier Editors Drafts and the First Public Working Draft include:
   <ul>
     <li>Making all properties cascade using the <a>writing mode</a> specified on the element, not on its parent.
     <li>Making the ordering of longhands within 'margin'-like shorthands put inline-start before inline-end.
