#1 id on html elements is not handled correct

[Jaap de Wolff]

the following source:
...
<htmli:tab id="Page28"
caption="Bladmuziek" onfocus="insertPage('28')">
<DIV STYLE="overflow: auto; width:
770px; height: 480px; border-left: 1px gray solid;
border-bottom: 1px gray solid; padding:0px; margin:
0px" Id="DivPage28" />
</htmli:tab>
...
is translated into:
...
<div htmli_class="com_htmli_ui_Tab" id="Page28"
htmli_caption="Bladmuziek" class="&#xA;
com_htmli_ui_Tab__selected&#xA; ">
<div id="Page28__inner">
<div id="ID0E6" style="overflow: auto; width:
770px; height: 480px; border-left: 1px gray solid;
border-bottom: 1px gray solid; padding:
0px; margin: 0px" id="DivPage28"
xmlns:htmli="http://www.htmli.com/ns/ui">
</div>
</div>
</div>
...
when instead if "Id" "id" is used everything works fine
