Ah, this is a problem with the publishing of Worg as the original org
file on Worg has the line.  Thanks for noticing this.  I have cc-ed the
org list.  

For the list:

In the org-beamer tutorial (Worg/org-tutorials/org-beamer/tutorial.org),
I have the following:

,----
| 
| #+BEGIN_Example
| ,** Two columns
| 
| ,*** A block                                           :B_ignoreheading:BMCOL:
|     :PROPERTIES:
|     :BEAMER_env: ignoreheading
|     :BEAMER_col: 0.4
|     :END:
|     - this slide consists of two columns
|     - the first (left) column has no heading and consists of text
|     - the second (right) column has an image and is enclosed in an
|       @example@ block
| 
| ,*** A screenshot                                            :BMCOL:B_example:
|     :PROPERTIES:
|     :BEAMER_col: 0.6
|     :BEAMER_env: example
|     :END:
| ,    #+ATTR_LATEX: width=\textwidth
|     [[file://../../images/org-beamer/a-simple-slide.png]]
| #+END_Example
`----

Note the second last line of the example which sets the latex attribute
for the following image.  On export to HTML for publishing on the Worg
website, this line has magically *disappeared*!  The ',' is supposed to
protect this line but instead it disappears.

I have gone through the whole tutorial and this is the only line that
has disappeared.  My intuition is that the HTML export is ignoring all
LATEX attribute lines (as it should) but that maybe the regex for is
rather greedy?  However, I have looked at the code but have not seen
anywhere obvious where this happens -- all the regexs I found seem to be
pinned at the start of the line with only whitespace allowed before
the #+.

I'll leave this for the exports methinks...
