DTD entities in XSLT

Hi,

trying to set up Saxon-JS 2 I hit a snag immediately, but I think the
question is general enough for this list.

The problem is DTD entities. Saxon-JS 2 documentation says:
"The XML parser used on Node.js skips any internal or external DTD.
Any named entity references appearing in a document will therefore be
flagged as errors, causing parsing (and hence transformation) to
fail."

Sure enough, when trying to generate the SEF file, I get an error:

Failed to compile stylesheet: Reference to unknown entity &typeahead;
at line 32 column 28
Error FODC0002
    Failed to compile stylesheet
Error FODC0002
    Reference to unknown entity &typeahead; at line 32 column 28

And all our stylesheets use a bunch of internal DTD entities (example below).
Would it be possible to somehow pre-process them and inline the
entities, so that I can keep them in the source file and still make
Saxon-JS happy?
