            Bug ID: 28535
           Summary: Missing definition for 'shape-rendering' property, or
                    bad example provided
           Product: SVG
           Version: SVG 1.1 Full
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Styling
          Assignee: schepers@w3.org
          Reporter: tristanlbailey@sgsoftware.com.au

Under '5 Document Structure' of the SVG 1.1 Second Edition specification, the
example titled 'Example Use04' contains the following line:

/* rule 7 */ use > path { shape-rendering: optimizeQuality }

However, no definition exists for an 'optimizeQuality' value of the
'shape-rendering' property, as can be seen via the following link:

11.7.3 The ‘shape-rendering’ property
http://www.w3.org/TR/SVG/painting.html#ShapeRenderingProperty

It has been suggested on the Internet that the 'optimizeQuality' value implies
that anti-aliasing is used.

Both the 'optimizeSpeed' and 'crispEdges' values discuss the turning off of
such a feature. It is not made clear if either the 'auto' or
'geometricPrecision' values make use of anti-aliasing.

Suggestions:
- Look at the definitions for 'optimizeSpeed' and crispEdges', and determine if
they should be made clearer as far as anti-aliasing is concerned.
- Determine whether or not the 'optimizeQuality' value is valid. If so, declare
it. If not, remove it from the example.
