Erik,

that's helpful, but not sufficient, as it were.
evidently it would not be possible to render in this instance.

can you please confirm whether processing should continue as normal,  
after the missing content?

also,

would it not be necessary or at least helpful, if as expressed and  
provided for in html, that a marker should be displayed, indicating  
that an image, or some graphical content is missing?

can this be incorporated into the specification?

kind regards

jonathan chetwynd
