OOB HTML5 plugin is removing the p/div elements which is authored with class attributes

Hi,

OOB HTML5 plugin is removing the authored elements (p, div etc)  when the class attribute is defined for that element. Instead if p/div elements, <span class="undefined_element" is enclosed between the authored text

Ex: add class/outputclass for p and div tags (<p class="p_test" otherprops="test" outputclass="telephone">507-123-1234</p>, <div class="divElement"> I am in div section</div>). Run the preset generation for the OOB HTML5 .

Authored p/div elements are stripping off in the generated html files, instead of authored content <span class="undefined_element"> is getting added if the class attributed is authored 

Below is the screenshot of the sample dita content

Generated HTML output without HTML5 customizations

OOB Plugin Customizations: Commented below code block in the topic.xsl.

Below is the screenshot of generated HTML5 page after OOB Customization. 

P/Div tags got stripped off in generated html5.

Could anyone guide me in retaining the same extact content along with the div/p elements with class attributes that are authored in the dita.

We are using latest version of fmdita -

Thanks,
