I think there is a better solution : write a custom DTD that
extends the DOCTYPE against which you are trying to validate
by making all well-formed constructs of the form

 <?php echo $clang;?>

legal within attribute values and anywhere else that you
wish to use them but which do not satisfy the formal
requirements for a Processing Instruction (PI), then
validate against that DTD.
