I plan to rewrite DynamicElement next weeks.
But on you problem, I'm not sure to understand.
When you have something like:
<gsweb name="MyDynamicElement" anAttr="attrValue"></gsweb>
Do you want to set attrValue or get it ? Do you have a concrete example ?

Summary:  REQ : Change to handling of Dynamic elements

Original Submission:  I'm currently putting together a website that uses title 
attributes heavily (accessibility and all that), and as a result I'm putting 
together a lot of dynamic elements.

I would like, for example, to use the title attribute of an input field to 
indicate error status.  However, once I've created the element, I can't get to 
its attributes, which become part of the htmlBareStrings.  I could deal with 
the attribute locally, but then I have to redo appendToRequest:inContext:.  It 
seems to me that it would be nice to be able to 'get at' the bare strings in a 
more accessible way, and to mutate them during the lifetime of the element.  
I've found that if I add an element to htmlBareStrings and then call parent 
appendToRequest:inContext:, the number of elements doesn't change, and I lose 
the end tag.

So.

I propose changes to GSWHTMLDynamicElement as follows:

First off, have an 'isStandalone' flag so we can make standalone tags generate 
the proper closing (See my other bug)

Next up, rip all the non-element attributes (i.e. those that would generate 
static attributes within the tag itself) into a dictionary, and redo the 
'drawing' code to use this instead of the current static string that is built.

that way, I can override appendToResponse:inContext: to create a new attribute 
dictionary 'on the fly', temporarily replace the existing dictionary, call 
superclass drawing code, then replace the original dictionary.

Would this work?
