DTD to XML Schema problem

[Usman Iqbal]

Hello,   I am a newbie to the XML world and have been assigned recently to convert a few DTDS that we were using at work to W3C XML Schema documents.   Our DTDs also use entities heavily, e.g. my DTD has a reference to a an entity for storing latin characters, <!ENTITY % ISOlat1 PUBLIC  "ISO 8879:1986//ENTITIES Added Latin 1//EN//XML" "ISOlat1.pen"> %ISOlat1;   and within that entity declaration we have entities of the form,       <!ENTITY Agrave  "&#192;" ><!-- capital A, grave accent -->     <!ENTITY Aacute  "&#193;" ><!-- capital A, acute accent -->     <!ENTITY Acirc   "&#194;" ><!-- capital A, circumflex accent -->     <!ENTITY Atilde  "&#195;" ><!-- capital A, tilde -->     My problem is, how to convert these entities into the W3C schema document, any help or advice in this direction would be highly appreciated.   Kind Regards, Usman Iqbal, PhD Student, University of New South Wales, Sydney, Australia
