Response from the Working Group
================================
RE your question about a web page saved as text -- it is no longer a web
page at that point and is not subject to WCAG.   That being said, it would
be good if the "save as text" routine would add the blank lines as per the
techniques to indicate headings.

We have added the following paragraph to the description:

"The programmatic identification of the Heading is the two blank lines
preceding it and one blank line succeeding it. Text documents are
necessarily void of underlying structure and so structure must be indicated
in the programmatic layout for screen readers. This programmatic layout will
enable screen readers to voice blank lines twice before the text that will
be considered as a heading.
A screen magnifier user would decipher headings by visually identifying the
space before it (or their technology may have Screen reader capabilities
that can identify the spaces)"
