There is difference between rpm and zip doc html files on rhel7 for tomcat7 and tomcat8. In "head" section the "meta" tag in zip looks like this:

<meta http-equiv="Content-Type" content="text/html" charset="ISO-8859-1">

whether for rpm this is how it looks like:

<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

Difference is in fact that in zip docs there is "charset" used as a separate attribute whether in rpm docs "charset" is part of "content" attribute.

According to this, "charset" as a separate attribute is allowed since HTML5. As in DOCTYPE is specified HTML 4.01 I presume that content in rpm docs is what we want regarding this discrepancy.

This is realy minor issue but it appears in our diff tool making more false-positive differencies.
