dot : label and xlabel with href generate broken SVG

Created by: jvkucera

Following simple example generates broken svg output (dot -Tsvg test.dot > test.svg).

digraph Test {

aaa[shape="box",href="http://www.google.com",label="google", xlabel=<<TABLE><TR><TD HREF="http://www.yahoo.com">yahoo</TD></TR></TABLE>>]; }

Problem in output SVG file is mismatched <a> and </a> tag.
