proposed changes and clarifications to p:load

in Section 7.1.13 p:load

it says

'If the value of the validate option is "true", namespace-aware DTD
validation is performed on the retrieved document. It is a dynamic
error (err:XC0027) if the document is not valid or the step doesn't
support DTD validation.'

should we not rename the option to precisely reflect its meaning

     <p:option name="dtd-validate"/>

also, is there clarification on schema validation that needs to be made here ?

also, should we consider an optional option that explicitly defines
what encoding to expect?

 <p:option name="encoding"/>
