Hhmm, I am not sure. From the specs:

<quote>
Validity constraint: Proper Declaration/PE Nesting

Parameter-entity replacement text MUST be properly nested with markup
declarations. That is to say, if either the first character or the last
character of a markup declaration (markupdecl above) is contained in
the replacement text for a parameter-entity reference, both MUST be
contained in the same replacement text.
</quote>

So, this would be a validation error, and Expat should not report it.
However, there is also this section:

<quote>
Well-formedness constraint: PE Between Declarations

The replacement text of a parameter entity reference in a DeclSep MUST
match the production extSubsetDecl.
</quote>

But it seems it doesn't apply here. So maybe Expat is OK?
