PROBLEM:
When editing Monorail views, you are losing the XHTML intellisense that normal webforms have in Visual Studio.

SOLUTION:
Add a proper xmlns to the html tag.
My layouts start with this:

   1:  <?brail 
   2:      output '<' 
   3:      output '?xml version="1.0" encoding="utf-8"?'
   4:      output '>' 
   5:  ?>
   6:  <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
                             "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
   7:  <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="he-il" lang="he" >

This applies to brail, but can of course be used on any other view engine, with the needed adjustments.

Lines 1-5 is needed due to a bug(?) in some versions of brail. brail used to recognize a script by '<? ?>', '<?brail ?>' and '<% %>' signs. therefore, using a <?xml ?> declaration caused the boo compiler to say that he knows nothing about 'xml'. I think that Ayende has solved the problem now, by allowing only '<?brail ?>', but I think it's not yet on the main trunk, so I still use the listed method.

Line 6 is the DOCTYPE, I use XHTML 1.0 transitional.

Line 7 is the magic part. Visual Studio parses this line, reads the xmlns, and can hint you with intellisense for html tags and attributes. The xml:lang and lang attributes are of course changeable.

It works in layouts, or in views that are a full html document (with <html> tag) but not with VieComponents or views that uses layouts.

If someone has a way to do that, please share it.
