The attributes of an HTML helper act like a dictionary, and they are in
fact stored in the .attributes attribute, which is a dictionary. So, you
can do any dictionary operations on .attributes (e.g., .pop). You can also
do some dictionary operations on the helper itself (without going through
.attributes), including accessing values via keys and using the .update
method.

No, it won't complain, though because the attribute is specified as a
keyword argument, it must be a legal Python identifier when using the above
syntax. Otherwise, you can use the alternative method for passing keyword
arguments:
form.element(_id='dude_int').update(**{'_custom-attr-with-hyphens':
'attr_data'})
If it is specifically a "data-" attribute, you can now also do:
form.element(_id='dude_int').update(data=dict(custom='attr_data'))
which will result in a "data-custom" attribute being added.
