The svg element from the SVG
namespace falls into the embedded content,
phrasing content, and flow content
categories for the purposes of the content models in this
specification.
When the SVG foreignObject element contains
elements from the HTML namespace, such elements must
all be flow content. [SVG]
The content model for title elements in the
SVG namespace inside HTML documents is
phrasing content. (This further constrains the
requirements given in the SVG specification.)
The semantics of SVG elements are defined by the SVG specification and other applicable specifications. [SVG]
The SVG specification includes requirements regarding the
handling of elements in the DOM that are not in the SVG namespace,
that are in SVG fragments, and that are not included in a
foreignObject element. This
specification does not define any processing for elements in SVG
fragments that are not in the HTML namespace; they are considered
neither conforming nor non-conforming from the perspective of this
specification.
