styleAttributeList()
Builds a string with a list of attributes to be used in a
style attribute.
Syntax
styleAttributeList(
   attrs om.SaxAttributes )
 RETURNS STRING
- attrs is the 
om.SaxAttributesobject defining the attributes. 
Usage
This function builds string containing a list of name:value; pairs, from the
attribute set defined by an om.SaxAttributes object.
The resulting string can then be used to define a CSS style, or it can be defined in an SVG
element using style="attribute-list".
Steps to define and use an attribute set with 
styleAttributeList():- Create and fill an 
om.SaxAttributesobject, - Create the SVG DOM element with one of the fglsvgcanvas functions,
 - Set the "style" attribute with value produced from 
styleAttributeList(). 
Example
CONSTANT COLORS_FIRE = 1
DEFINE attr DYNAMIC ARRAY OF om.SaxAttributes,
       n om.DomNode
...
LET attr[COLORS_FIRE] = om.SaxAttributes.create()
CALL attr[COLORS_FIRE].setAttribute(SVGATT_STROKE,"red")
...
LET n = fglsvgcanvas.circle(100,100,50)
CALL n.setAttribute(SVGATT_STYLE, fglsvgcanvas.styleAttributeList(attr[COLORS_FIRE]) )
...
