Function el

el(
    name: string,
    attrs?: Record<string, string>,
    ...children: (XmlNode | (XmlNode | null | undefined)[] | null | undefined)[],
): XmlElement
Builds an XmlElement. Nullish children are dropped and arrays are flattened, so conditional children (cond ? el(...) : null) and spread lists compose cleanly.
Parameters
- name: string
  The tag name (include a prefix if needed, e.g. stream:features).
- attrs: Record<string, string> = {}
  Attribute map; omit or pass {} for none.
- ...children: (XmlNode | (XmlNode | null | undefined)[] | null | undefined)[]
  Child elements or text; null/undefined are skipped, arrays flattened.
Returns XmlElement
The constructed element.

```
import { el, serialize } from 'edgeport/xmpp';

const iq = el('iq', { type: 'get', id: '1' }, el('query', { xmlns: 'jabber:iq:roster' }));
serialize(iq); // <iq type="get" id="1"><query xmlns="jabber:iq:roster"/></iq>
```
