Shortcode parameter names can't have dashes in them

[Viper007Bond]

I expected this to work, but it doesn't:

[tag my-param="value" foo="bar"]Hello world![/tag]

The passed array looks like this:

array( 
	0 => 'my-param="value"',
	'foo' => 'bar'
);

function is shortcode_parse_atts() in wp-includes/shortcodes.php

the parsing is done by regular expressions.

word limiters are used, I guess dashes are not supported by them.

I wonder if it makes sense. This problem can for easier besolved by clarifying the documentation, the regular expression pattern is already quite complex.

it's supposed to "look" like html attributes. curious to know if dash is a valid character for html attributes before closing as invalid...

Some HTML Trivia:

• attribute names are not case sensitive. (HTML 2.0)
• The `NAMELEN' parameter in the SGML declaration (section SGML Declaration for HTML) limits the length of an attribute value to 1024 characters.
• HTML allows CDATA attributes to be unquoted provided the attribute value contains only letters (a to z and A to Z), digits (0 to 9), hyphens (ASCII decimal 45) or, periods (ASCII decimal 46)
• An attribute specification consists of a name, an "=" and a value specification. The name refers to an item in an ATTLIST declaration.

I see no attribute name in HTML (2.0, 3.2, 4.1 & xhtml 1.0) that conatins a dash or dot.
