Yes, but you need to know what attributes you want to use and set those
in UseModifier. Using dynamic options is kind of difficult with IC 4.6.x,
but is made a bit easier in 4.7.x.

The fieldsize=20 isn't going to help you; you would need to have a size_limit
field to do something there. I will show use of that below.

Don't you have a unique key in attr? If you don't you don't even need to make
it a database. I tested the below with an attr.txt file of:

prodid	fieldtype	fieldname	parms	size_limit
1001	text_20	Engraving		20
1001	radio	Size	Small, Medium, Large


<FORM>
        [loop search="
                fi=attr.txt
		st=text
                co=yes
                sf=prodid
                se=1001
                rf=fieldtype,fieldname,parms,size_limit
             "]
        [accessories
                attribute="[loop-param fieldname]"
                type="[loop-param fieldtype]"
                passed="[loop-param parms]"
            [if-loop-param size_limit]
                filter="[loop-param size_limit]"
                extra="MAXLENGTH=[loop-param size_limit]"
            [/if-loop-param]
        ]
        [/loop]
</FORM>

Be careful -- this takes advantage of the fact that all of the
[loop-TAG ..] stuff is inserted before the accessories tag is evaluated;
bear in mind you can't do [if type term] [/if] stuff inside the body of
a tag. People often get confused there, and not surprising, I guess. 8-)
