I have small problem with Xmlize and containers. The XML will look like this:

<cats>
    <item>...</item>
    <item>...</item>
    ...
</cats>

That is not very XMLish. I want:

<cats>
    <cat>...</cat>
    <cat>...</cat>
    ...
</cats>

Could we add this to XmlIO class:

class XmlIO {
...

public:
...
	template <class T> XmlIO operator()(const char *tag, const char *itemtag, T& var);

and after:

template <class T>
void Xmlize(XmlIO xml, const char* itemtag, T& var)
{
	var.Xmlize(xml);
}

...

template <class T> XmlIO XmlIO::operator()(const char *tag, const char *itemtag, T& var) {
	XmlIO n(*this, tag);
	Xmlize(n, itemtag, var);
	return *this;
}

...

template<class T>
void Xmlize(XmlIO xml, const char* itemtag, Vector<T>& data)
{
	XmlizeContainer(xml, itemtag, data);
}

...

template<class T>
void Xmlize(XmlIO xml, const char* itemtag, Array<T>& data)
{
	XmlizeContainer(xml, itemtag, data);
}

This change is only meant for Array and Vector marshaling, but could be extended to rest of the containers.

So now I can do:

xml("cats", cats);

for the original XML format, or:

xml("cats", "cat", cats);

for the format I want.

I have no problem adding this. Could you post a complete patch please?
