    <!--
      The task calculates SourceLink URL for a given SourceRoot.

      If the SourceRoot is associated with a git repository with a recognized domain the <see cref="SourceLinkUrl" />
      output property is set to the content URL corresponding to the domain, otherwise it is set to string "N/A".

      Recognized domains are specified via Hosts (initialized from SourceLinkGitWebHost item group).
      In addition, if SourceLinkHasSingleProvider is true an implicit host is parsed from RepositoryUrl.

      Example of SourceLinkGitWebHost items:

      <ItemGroup>
        <SourceLinkGitWebHost Include="myGitWeb1.com" ContentUrl="http://myGitWeb1.com" />
        <SourceLinkGitWebHost Include="myGitWeb2.com" />           ContentUrl defaults to https://myGitWeb2.com
        <SourceLinkGitWebHost Include="myGitWeb3.com:8080" />      ContentUrl defaults to https://myGitWeb3.com:8080
      </ItemGroup>

      ContentUrl is optional. If not specified it defaults to "https://{domain}" or "http://{domain}", based on the scheme of SourceRoot.RepositoryUrl.
