preserving attributes

I'm having trouble preserving attributes of HTML tags.

here is part of my file:

<H1 class=ArticleHeading>This is the heading</H1>
<H2 class=byline>This is the byline</H2>

after converting the above to XHTML using TidyCOM (based on 8 July 2000
version of TIDY) I get the following:

<H1>This is the heading</H1>
<H2>This is the byline</H2>

What do I need to do to preserve the attributes??
Thanks in advance
