expand_entity: :never does not preserve the 
 entity as expected #136
Description
Hello,
I'm using Saxy to parse .docx files, and I need to preserve certain entities exactly as they appear in the XML content—for instance, (line feed) present in attributes such as o:gfxdata.
According to the documentation, the expand_entity: :never option is supposed to keep entity references literal in the output (rather than converting them to the character \n). However, in my tests, still ends up converted or normalized, and I no longer see in the resulting DOM structure.
Minimal example:
xml = ~s|<tag attr="Base64
MoreBase64" />|
{:ok, dom} = Saxy.SimpleForm.parse_string(xml, expand_entity: :never)
# Expected behavior: the attribute value should remain "Base64
MoreBase64".
# Actual behavior: the entity 
 seems to be turned into something else.
IO.inspect(dom)
The specification for the :never setting suggests that the entity should not be resolved, i.e., it should be emitted as in the final structure. Is this a bug, or is there an internal XML normalization step affecting line feeds in attributes?
Thank you in advance for your help!
