You can add comments to the XAML file using SSI formatting:
<!-- Grid Styles -->
<style...>
<style...>
<!-- Window Styles -->
<style...>
<style...>
<style...>
This at least gives you some sort of "header" if you use the built-in XML collapse.
In Visual Studio 2012 Update 4, I was able to select a very large section of XAML code, right click and choose "hide selection". (basically collapses that section with the [...] notation, and after expanding it, the system "remembers" that I wanted to collapse that portion with the [-] notation next to the line numbers.
