In your community what percentage of XML users/developers use these technologies: Namespaces, XML Schema, Schematron, ...

Hi Folks,

I wish to get a feel for what XML technologies people are using in various communities. Nothing precise, just a rough idea. 

In the community that I work in, here is my estimate, for this technology selection, of the percentage of XML users/developers that use the technologies:

1. Namespaces:  > 99%

2. XML Schema:  >95%

3. Schematron:  30% (and rising yearly)

4. RelaxNG:  <1%

5. XSLT:  20%

6. XProc: <1%

7. RDF:  5%

8. OWL: 5%

9. RSS: 5%

10. ATOM: 1%

11. NVDL: <1%

What are the percentages for your community?
