Problem

The problem in above issue were that two styles had similar names but different style:family, which lead to unintended formatting. See https://bugs.documentfoundation.org/show_bug.cgi?id=155244

Solution

Making ODF style IDs unique for HTML/CSS by adding a prefix (the @style:family with '-' as glue character) to their style name.

Solution Details

• Adding a prefix (the @Style:family with '-' as glue character) to each style name twice:
  1. in the CSS header for each style name
  2. in the HTML body for each style name
• Added a function (XSLT named template) to map an element name to a style:family to get the the @style:family in the body
• Enhanced the mapping of all style attributes to create a single CSS class attribute with all style names a space separated list of this class attribute (trimming the value later). Wasting just a bit of performance as in case of multiple style names each will create an class attribute and overwrite the prior (but XSLT is not C++) ;-)
