This is a sample document that illustrates the markup
structure of a conformant XHTML+Voice document.
Notice that the default XML namespace is XHTML --and
consequently, standard HTML element names do not need
a namespace prefix. We can add voice-interaction
specific elements from the Voice XML 2.0 namespace
using prefix vxml
. We can attach event
handlers using prefix ev
. Clicking
anywhere on this paragraph results in a welcome
message being spoken on account of attaching a
vxml:form
handler to this paragraph.
