Context and xypic, amslatex etc

[Marko Schuetz <MarkoSchuetz@web.de>]

I am  new to context and  thought I'd ask: likely  someone has already
tried this.

Currently I use:

\documentclass[a5paper,DIVclassic,10pt,twoside,smallheadings]{scrbook}
\usepackage[fleqn]{amsmath}
\usepackage{amsthm}
\usepackage[english]{babel}
\usepackage[latin1]{inputenc}
\usepackage[all]{xypic}
\usepackage{graphicx}
\usepackage{epsfig}
\usepackage{code}
\usepackage{makeidx} 
\usepackage{amsfonts}

I assume that context already includes the functionality of some of
these, like graphicx and epsfig.

Will I have trouble with the others? Are there replacements for the
others to work with context? 

Thank you for your help

Marko
