The idea is just to remove the ugly if else with is there, no then create.
> Non unique IDs generated by IndexingSink

> Key: DOXIA-662
> URL: https://issues.apache.org/jira/browse/DOXIA-662
> Project: Maven Doxia
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.0.0-M3
> Reporter: Konrad Windszus
> Priority: Major
>
> If a HTML source contains non-unique headlines (i.e. two or more headlines
> with the same text) in a single HTML page the IDs being generated out of
> those are not unique.
> That leads to issues with e.g. the TOC macro
> (https://github.com/apache/maven-doxia/blob/2aea4500ba6559b91fe3a4b83a5d3aafc10116b4/doxia-core/src/main/java/org/apache/maven/doxia/macro/toc/TocMacro.java#L155)
> which writes an anchor link leveraging that id.
> The problematic line is

> which just uses the (sanitized) title as id. In case of conflicts the title
> needs to be suffixed with an index to be unique.
