Can't you just do something like:

  <Project DefaultTargets="Build" ToolsVersion="4.0">
    <ItemGroup Label="ProjectConfigurations">
       <#list profiles as p>
         <ProjectConfiguration Include="${p.configuration}|${p.platform}">
           <Configuration>${p.configuration}</Configuration>
           <Platform>${p.platform}</Platform>
         </ProjectConfiguration>
       </#list>
     </ItemGroup>
     ...
  </Project>

If you need to generate those pieces in multiple rounds (calling Maven
again and again), and only after that insert them, then it sounds like
you need those little templates, save their output with a known name
somewhere, and then for the insertion you do something like:

  <Project DefaultTargets="Build" ToolsVersion="4.0">
    <ItemGroup Label="ProjectConfigurations">
       <#list profiles as p>
         <#include p + "_ProjectConfiguration.ftl">
       </#list>
     </ItemGroup>
     ...
  </Project>
