Sometimes that is teh right thing to do, but it's far from being always
correct and really works against the intended usage of entity

An entity reference is supposed to be an ___author convenience_ that
does not affect further processing.

So if you have the usual "modified identity transformation" idiom that
has an identity transformtaion and then extra templates to make specific
changes, say
<xsl:template match="x"><y/><xsl:template>
to change x to y, then in a document such as
<!ENTITY x "<x/>">

is supposed to work the same way as


and the element x needs to be transformed. If you need to preserve the
entity reference you need to change its definition, resulting in

<!ENTITY x "<y/>">
